Back Pain
Red Flags — the 5% with specific serious pathology; must ask; must document
| Red flag | Diagnosis to exclude | Action |
|---|---|---|
| Saddle anaesthesia + bladder/bowel change | Cauda equina syndrome — cord compression at the cauda equina causes bilateral S2-S5 nerve dysfunction: saddle numbness (perianal; perineal; inner thighs); urinary retention (most common — loss of urge; overflow); faecal incontinence; bilateral leg weakness. Emergency MRI needed within 4 hours. Neurosurgical intervention reduces risk of permanent neurological deficit if performed within 24–48 hours of onset. Document asking these questions at every consultation. | 999 or same-day A&E — emergency MRI — neurosurgery |
| Bilateral progressive leg weakness | Cauda equina or spinal cord compression (myelopathy). Bilateral leg weakness rapidly worsening even without saddle symptoms: emergency assessment. Myelopathy (cord compression above L1): upper motor neurone signs (hyper-reflexia; upgoing plantar; clonus); bilateral spastic paraparesis; bladder dysfunction. Distinguish from bilateral radiculopathy (LMN pattern). | 999 or same-day A&E — urgent MRI full spine |
| Age >50 + weight loss + night sweats | Spinal metastases — most common primary sites: prostate (men); breast (women); lung; kidney; thyroid; myeloma. Back pain is the most common presentation of spinal metastases. Features: constant pain; not relieved by rest (often worse lying down); thoracic location (more suspicious than lumbar); age >50; previous cancer history; systemic features (weight loss; fatigue; anaemia). PSA in men; mammography/CT in women if risk. Urgent MRI spine. | Same-day urgent assessment; urgent bloods; urgent MRI; 2WW referral if cancer suspected |
| Fever + back pain + immunocompromised | Vertebral discitis (spinal infection) or epidural abscess. Risk factors: IV drug use; immunocompromised (DM; HIV; steroid therapy; post-transplant); recent spinal procedure; bacteraemia (urinary tract infection; skin infection; endocarditis). Features: fever; night sweats; exquisite tenderness on spinal percussion; raised CRP and WBC; gradually worsening pain at rest. MRI is imaging of choice. IV antibiotics; neurosurgery if abscess with cord compression. | Same-day hospital admission — MRI; blood cultures; IV antibiotics |
| Acute LBP + corticosteroid use / age >70 / trauma | Vertebral compression fracture — risk factors: osteoporosis (post-menopausal women; men on long-term steroids); age >70; trauma (may be trivial in severe osteoporosis — coughing; bending). Features: acute onset of severe midline spinal pain; worse on movement; localised tenderness. X-ray may show vertebral height loss but MRI (or DEXA) provides more information. Treat fracture + underlying osteoporosis (calcium; VitD; bisphosphonate; orthopaedic review). | X-ray; MRI if X-ray negative and high suspicion; DEXA; bone protection; orthopaedic review |
| Thoracic back pain (not lumbar) | Thoracic back pain is less commonly mechanical than lumbar pain and should prompt suspicion of serious pathology: aortic dissection (sudden; tearing; to abdomen); spinal metastases (thoracic spine more often than lumbar for haematogenous spread); pancreatitis (referred to mid-back); pulmonary embolism (pleuritic; with respiratory symptoms); cardiac referred pain. Thoracic mechanical pain exists but is a diagnosis of exclusion in the GP setting. Urgent assessment if sudden onset; cardiovascular risk factors; constitutional symptoms. | Urgent assessment; ECG; CXR; bloods; consider 999 if acute cardiovascular cause possible |
Safeguarding — Domestic Violence; Occupational Considerations; Mental Health Risk in Chronic Pain
💔 Domestic violence
- Back pain can result from assault; inconsistency between mechanism and injury should prompt concern
- NICE-recommended routine enquiry for domestic violence in all patients attending with pain, especially if pattern of repeated attendance
- Ask in private (never with partner present): “Sometimes when people are in pain or distressed, it can be related to what’s happening at home. Is everything OK at home?”
- Refer to MARAC; DA support services if concern
💼 Occupational factors
- Manual handling injury at work: RIDDOR reporting obligation if meets threshold; employer must be notified; sick note requirements
- Construction; logistics; healthcare workers: high-risk occupations for repetitive lifting — occupational health referral if workplace modification needed
- David: office worker working from home — ergonomic assessment of home workstation; return to work planning; employer communication if needed
- Fit note (MED3): most patients should be encouraged to stay at work or return quickly; “may be fit for work” options available
💕 Mental health — chronic pain and depression
- Depression and anxiety co-exist with chronic LBP in up to 30–40% of patients; each worsens the other
- PHQ-9 and GAD-7 at any review of chronic LBP (>12 weeks)
- Chronic pain + social isolation + carer burden (David’s wife has MS): cumulative risk for depression
- Refer to NHS Talking Therapies; pain management programme (CBT component) if depression contributing to chronification
🏠 Carer burden — David’s specific context
- David is the primary carer for his wife who has MS: his back pain is not just a personal health issue — it threatens his ability to care for his wife, which is a significant additional stressor
- Ask specifically about this: “I know you are caring for your wife at home — how has your back pain affected your ability to do that? Is your wife getting all the support she needs?”
- Carer’s assessment: David may be eligible for a carer’s assessment under the Care Act 2014; social services referral if wife’s care is at risk during David’s incapacity
- Alternative care arrangements for wife: emergency carer support if David is unable to care
😱 Fear Avoidance Beliefs
David has been resting completely for 2 weeks because he believes that movement will worsen his back. This is fear avoidance — a pattern where fear of pain-related harm leads to avoidance of activity, which leads to deconditioning, which worsens pain, which increases fear. It is one of the strongest predictors of chronic LBP. The GP must address it explicitly and early: "Movement is not harming your back — it is treating it."
"I want to talk about the resting, because I think it might actually be working against you. I know it sounds counterintuitive, but back pain gets worse with rest. Movement — gentle, graduated — is one of the most important treatments we have. Can I tell you why?"💔 Catastrophising
David believes he has a "slipped disc" and fears surgery. Catastrophising — the belief that pain equals irreversible structural damage, or that the worst case scenario is inevitable — amplifies pain perception and drives care-seeking behaviour (including demands for imaging). Correcting the catastrophising belief with specific, accurate information (most disc herniations resolve; 95% of sciatica never needs surgery) is both therapeutic and educational.
"I understand why you’re thinking about surgery — but I want to tell you something reassuring: 95% of people with exactly the kind of pain you are describing — back pain with leg pain — never need surgery. And most get completely better."🏠 Carer Burden
David is the primary carer for his wife who has MS. His back pain disrupts his caring capacity, which generates anxiety (which worsens pain) and a sense of failure (which generates depression risk). This creates a cycle: more pain → less able to care → more anxiety → more pain. The GP must acknowledge this explicitly: "I can see that not being able to care for your wife properly is making this much harder." Carer’s assessment and emergency care plan for wife are important.
"Can I ask — how is your wife managing while you’ve been laid up? Is she getting all the support she needs? I want to make sure we have a plan for both of you."💻 Occupational Context
David has been off work for 2 weeks as an office manager. Prolonged sickness absence is itself a risk factor for chronic pain and chronic disability — the longer a patient is off work with LBP, the lower the probability of returning. NICE NG59: encourage return to work as soon as possible — being at work does not worsen LBP and is beneficial for mental health. Phased return; adjusted duties; ergonomic workstation assessment. Fit note: "may be fit for work" with modified duties is more appropriate than full sick leave for most office workers with LBP.
"One thing I want to raise: getting back to some work — even from home; even with reduced hours — is actually better for your back than staying off. The evidence is really clear: working, even through some pain, helps people recover faster. Can we talk about how to make that work for you?"- Not asking about cauda equina features and not documenting that they were asked — this is the most common medico-legal failure in back pain consultations; must ask; must document
- Not exploring yellow flags (fear avoidance; catastrophising; carer role) — these are more predictive of outcome than clinical findings and must be identified early
- Validating the rest without challenging it — rest is harmful; the GP who says "yes, take it easy" is reinforcing the most important yellow flag
999 / Same-Day A&E
Immediate action- Cauda equina syndrome — saddle numbness + bladder/bowel change999; same-day emergency MRI; neurosurgery — outcome depends on surgical speed
- Bilateral rapidly progressive leg weaknessCord compression or CES; 999; urgent MRI full spine
- Suspected aortic dissection (thoracic pain; tearing; cardiovascular risk)999; ECG; CXR; urgent CT aorta
- Spinal epidural abscess with cord compression (fever + progressive neurology)999; MRI; IV antibiotics; neurosurgery
Urgent Assessment / Referral
Days to 1 week- Red flags — suspected malignancy; age >50 + weight loss + cancer historyUrgent bloods (FBC; CRP; PSA; calcium; LFT); urgent MRI; 2WW referral
- Vertebral discitis (fever + worsening back pain)Same-day hospital; blood cultures; MRI; IV antibiotics
- Vertebral compression fracture (trauma + osteoporosis risk)X-ray; bone protection; orthopaedic review
- Rapidly worsening sciatica with progressive neurological deficitMRI within 1 week; urgent orthopaedic/neurosurgery review if deficit progressing
Non-specific LBP / Sciatica
GP-managed; exercise first- Non-specific LBP (David — no red flags; radiculopathy but stable)NSAIDs; physiotherapy; exercise; yellow flag management; fit note
- Sciatica (<6 weeks) with no progressive neurological deficitConservative management; physiotherapy; MRI at 6–8 weeks if not improving
- Suspected axial SpA (inflammatory features; <45)NSAIDs (therapeutic + diagnostic); HLA-B27; CRP; rheumatology referral
- Not documenting cauda equina features specifically — if it is not in the notes, it was not asked
- Not performing SLR when the history suggests radiculopathy — SLR is the key confirmatory test for sciatica and should always be documented if leg pain is present
- Not documenting neurological examination findings — if neurology deteriorates later, the baseline must be recorded
- Ordering MRI for David at 3 weeks without red flags or progressive neurological deficit — not indicated; NICE NG59; does not improve outcome; may worsen catastrophising by finding incidental changes
- Ordering X-ray "to check the disc" — X-ray does not show discs or nerve roots; exposes to radiation without benefit
"What is happening in your back is that one of the discs between your vertebrae — the cushioning pads — is bulging slightly out of its normal position and pressing on the nerve that runs down your left leg. That nerve is called the L5 nerve root, and when it is irritated, it causes exactly the pain and tingling you are getting down to your big toe. The disc has not ‘slipped’ — that is not really what happens. Think of it more like a jam doughnut: the jelly inside has pushed out slightly to one side. The good news is that for the vast majority of people — about 95 out of 100 — this resolves completely without surgery. The nerve inflammation calms down, the disc stabilises, and the pain goes. Most people are significantly better within 6–8 weeks. And the most important treatment is movement — not rest."
"I have a slipped disc and I need surgery."
"Most people with exactly the pain pattern you have — back pain with leg pain down to the foot — never need surgery. Surgery is considered in about 5% of cases, and only after conservative treatment has been tried for at least 6–8 weeks and specifically if there is a significant neurological deficit getting worse. You don’t have that. The research is very clear: exercise and physiotherapy give equivalent results to surgery for most people with sciatica, and without the surgical risks."
"Resting is protecting my back."
"I know this feels counterintuitive — when something hurts, it feels natural to protect it. But for back pain, we know from decades of research that rest makes things worse, not better. The muscles that support your spine weaken; the disc becomes less well-nourished; and psychologically, the longer you avoid movement, the more frightening it becomes. The treatment for sciatica is graduated movement — physiotherapy to teach you the right movement, and then exercise to build up gradually."
Axial spondyloarthropathy
If morning stiffness >1 hour; age <45; improves with exercise; alternating buttock pain; uveitis; psoriasis; IBD. HLA-B27; CRP; MRI SI joints; rheumatology.
Piriformis syndrome / myofascial pain
Deep buttock pain; piriformis tender; sciatica-like without true radiculopathy; SLR negative; treated with stretching; physiotherapy. Exclude by response to targeted physiotherapy.
Cauda equina syndrome
Saddle anaesthesia; bladder/bowel change; bilateral weakness. Absent in David. Must be documented as specifically asked about and found absent.
Spinal malignancy
Constant pain; worse at night; weight loss; age >50; cancer history. Absent in David. Document systematic red flag screen.
- Telling the patient they have a "slipped disc" without explaining what that means and correcting the catastrophic model — reinforces fear avoidance
- Not addressing the fear of surgery directly — David’s primary concern; leaving it unaddressed means he leaves still frightened
- Deferring physiotherapy referral until after MRI — conservative management is effective regardless of imaging findings; waiting delays appropriate treatment
Validate — "I completely understand why you want a scan"
Never mock or dismiss the request for imaging. David’s desire for a scan comes from a reasonable place: he wants to know what is wrong; he is in pain; and the scan represents certainty. The GP who rolls their eyes or says "you don’t need a scan" without explanation damages the therapeutic relationship and invites non-compliance.
"I completely understand why you want an MRI — if something is wrong, it makes complete sense that you would want to see it. Let me explain what we know about imaging at this stage, and then you can tell me what you think."Explain — evidence-based reasoning, not just "it’s not NICE guidelines"
The GP must explain specifically why MRI at 3 weeks does not help, not just invoke protocol. Three specific reasons: (1) it does not change treatment at this stage; (2) 30–40% of asymptomatic adults have disc findings on MRI — the scan finding may not be the cause of the pain; (3) knowledge of an MRI finding can worsen catastrophising and fear avoidance.
"Here is the thing about MRI at this stage: even if we did it today, it would not change what we do — because the treatment right now is the same either way: physiotherapy and graduated movement. And here is something important: if we scan 10 people with no back pain at all, 3 or 4 of them would have a disc bulge on the MRI — but they feel completely fine. The scan shows structure, not cause."Negotiate — offer MRI at 6–8 weeks as a specific commitment
Never leave a patient with a refused request and no alternative. The offer of MRI at 6–8 weeks if not improving is not a consolation prize — it is the clinically appropriate plan. Stating it clearly and booking a specific review appointment transforms a refusal into a plan.
"What I want to do is start the physiotherapy and the medication today, review you in 6–8 weeks, and if you are not significantly better at that point, we arrange the MRI then — because that is when it would genuinely help us decide whether anything else is needed. I am going to book that review today so it is in the diary."Walking is one of the most evidenced non-pharmacological interventions for acute LBP. It loads the spine appropriately; activates paraspinal muscles; releases endorphins; prevents deconditioning; and reduces fear avoidance by demonstrating that movement is tolerated. The key message: some pain during walking is expected and does not mean harm.
Start at a comfortable pace for 10 minutes twice daily. Increase by 5 minutes per session every 2–3 days as tolerated. Use good posture (head up; shoulders relaxed; arms swinging naturally). Avoid walking hunched. Goal: 30 minutes continuous walking by weeks 2–3.
NICE NG59: offer an exercise programme as first-line treatment. Individual or group; biomechanical; aerobic; mind-body; or a combination. For David’s L5 radiculopathy: physiotherapist will assess neural tension; prescribe specific nerve mobilisation exercises (neural flossing); core stabilisation; McKenzie directional therapy (which direction reduces leg pain — usually extension-based for posterior disc herniation).
Refer to NHS MSK physiotherapy today. While awaiting: McKenzie exercises (prone-lying; press-ups from floor); walking; gentle core activation (pelvic tilts). Physiotherapy is as effective as surgery for sciatica (SPORT trial; RCTs) — communicate this to David.
NICE NG59 specifically names yoga and Pilates as appropriate exercise forms for LBP. Yoga: reduces pain scores and improves function in chronic LBP (multiple RCTs). Pilates: strengthens core stabilising muscles (multifidus; transversus abdominis) that protect the lumbar spine. Swimming: unloads the spine; provides aerobic exercise; safe during acute sciatica.
Swimming: recommended from early stages; breaststroke may aggravate lumbar extension — front crawl safer for sciatica. Yoga: begin with gentle class; inform instructor about sciatica so they can modify poses. Pilates: reformer or mat; inform instructor. GP can refer to social prescribing for exercise on prescription.
NICE NG59: encourage staying at or returning to work as soon as possible — work does not worsen LBP and is independently associated with faster recovery and better long-term outcomes. Longer sickness absence increases risk of chronic LBP and depression. Office work (David’s context): can usually be returned to within 1–2 weeks with ergonomic adjustments.
Fit note (MED3): “may be fit for work” with: working from home; 4-hour days initially; no heavy lifting; standing desk or sit-stand arrangement; regular movement breaks. Ergonomic assessment of home workstation (chair height; screen height; lumbar support). Employer communication letter if needed. Do not issue “unfit for all work” if modified duties possible.
Fear avoidance beliefs and catastrophising are the strongest predictors of chronic LBP. Addressing them at the first consultation — with education about the biopsychosocial model; reassurance about safety of movement; and normalising some pain during activity — reduces chronification risk. If yellow flag burden is high (David has several): NHS Talking Therapies/CBT referral alongside physiotherapy gives better outcomes than either alone.
Pain education at this consultation: “pain does not equal damage; movement is safe; the nerve is inflamed not permanently damaged.” Leaflet / NHS LBP resources. If high fear avoidance: refer to NHS Talking Therapies for CBT. Pain management programme (PMP) if chronic LBP developing (>12 weeks). Social prescribing: support for carer burden (wife with MS).
NICE NG59: may offer heat or ice as short-term adjunct to active management. TENS: NICE does not recommend for chronic LBP. Heat (hot water bottle; heat pad): reduces muscle spasm; increases tissue extensibility; evidence for short-term pain relief in acute LBP. Ice: reduces acute inflammation; use in first 48–72 hours for acute episode; wrap in towel (never directly on skin). No evidence for superiority of heat over ice — patient preference guides choice.
Heat pad or warm bath: 15–20 minutes 2–3 times daily for comfort. Ice pack (wrapped): 10–15 minutes after exercise to reduce inflammation. Avoid prolonged heat or ice use — this is an adjunct to, not a replacement for, active exercise therapy. Do not prioritise passive over active management.
- Ibuprofen 400–600mg TDS with food; OR naproxen 500mg BD with food
- Naproxen preferred: better CV safety profile; BD dosing (improved adherence)
- Add omeprazole 20mg OD for gastric protection (David is 42; below the age >45 threshold but NSAID + any PPI risk)
- Lowest effective dose; shortest effective course (aim 2–4 weeks; reassess)
- Review if pain not controlled: consider step up to COX-2 inhibitor (etoricoxib 60mg OD) for better GI profile
- Codeine 30mg QDS PRN (not regular): add-on if NSAIDs inadequate; short course (maximum 1–2 weeks)
- Tramadol 50–100mg QDS: alternative; Schedule 3 CD; serotonin syndrome risk
- Never prescribe opioids as monotherapy (without NSAID or exercise plan)
- For chronic LBP: avoid opioids — evidence of harm > benefit in chronic back pain
- Gabapentinoids (pregabalin; gabapentin): NICE NG59 — do NOT offer for LBP or sciatica; no evidence of benefit; significant harms (sedation; dependence; Schedule 3)
- Paracetamol alone: NICE NG59 — not recommended for LBP (Cochrane 2016: no better than placebo)
- Strong opioids (morphine; oxycodone) for chronic LBP: evidence of harm > benefit; dependence; hyperalgesia; mortality risk
- Diazepam long-term: 2–7 days only for acute muscle spasm; never for chronic LBP; dependence
- Amitriptyline 10mg at night: titrate to 25–50mg; evidence for chronic LBP (analgesic + sleep benefit); not for acute LBP
- Duloxetine 30mg OD titrated to 60mg: NICE endorses for chronic LBP; especially if comorbid depression or anxiety; evidence from NICE NG59
- Referral to pain management programme (multidisciplinary: CBT; physio; OT; pharmacology)
- Axial SpA: NSAIDs are dramatically effective (diagnostic + therapeutic); COX-2 inhibitors licensed in AS
- Muscle spasm (acute): diazepam 2mg TDS for 2–7 days only; warn about drowsiness; no driving; no alcohol
- NSAIDs + anticoagulant: avoid if possible; use paracetamol + codeine; or COX-2 + gastric protection
- Renal impairment: avoid NSAIDs; use paracetamol + codeine; or tramadol (reduce dose in renal failure)
Select patient characteristics — back pain medication guidance
"I am prescribing naproxen — an anti-inflammatory tablet — twice a day with food. Always eat something before taking it — it can irritate the stomach on an empty stomach. I am also prescribing a stomach-protecting tablet to take with it. The goal is to take the edge off the pain enough so you can do the physiotherapy and the walking — which is the real treatment. Take it for 2–4 weeks and we will review whether you still need it."
Naproxen 500mg BD: preferred NSAID for LBP (twice-daily dosing; better CV safety; first-line NICE NG59). Always prescribe with omeprazole 20mg OD. CI: active PUD; severe renal impairment; severe heart failure. NOT paracetamol alone (NICE: no better than placebo for LBP). NOT gabapentinoids (NICE NG59: not recommended for non-specific LBP — most common SCA prescribing error).
"Always take with food. If you are already taking aspirin, take the aspirin at least 30 minutes before the ibuprofen. Use the lowest dose that controls the pain and only for as long as you need it."
Ibuprofen: widely used; OTC available; consider prescription-strength (600mg TDS) if OTC dose inadequate. Disadvantages vs naproxen: TDS dosing (adherence); slightly higher GI risk; higher CV risk at high doses. If aspirin co-prescribed: take aspirin first (30+ minutes) — ibuprofen may block aspirin’s antiplatelet effect.
"This tablet is for the worst moments — when the pain is preventing you from sleeping or from doing your physio exercises. Take it as needed, not regularly. It can make some people constipated, so drink plenty of water and eat plenty of fibre. Do not drive if it makes you drowsy. This is for 2 weeks — I want to review whether you still need it before prescribing more."
Codeine: step 2 add-on (not monotherapy) for LBP when NSAIDs alone insufficient. PRN not regular. Maximum 2 weeks without review. NEVER for chronic LBP (harms exceed benefits; dependence; hyperalgesia). Constipation: always warn and consider laxative. SCA point: prescribing codeine (or tramadol) as a first-line prescription for LBP without NSAIDs and physiotherapy = Tasks deduction.
"This is a low-dose tablet that helps the way your nervous system processes pain — it works on the pathways in the spinal cord that modulate pain signals. It also helps your sleep, which is important because poor sleep makes pain worse. Take it at night — it will make you sleepy at first. It takes about 4–6 weeks to feel the full benefit. You may notice a dry mouth — that is normal."
Amitriptyline 10mg OD at night: for chronic LBP (>12 weeks); NOT acute LBP; titrate to 25–50mg; 4–6 weeks for full effect; sleep benefit. NICE NG59 endorses low-dose TCA for chronic LBP. Not for acute LBP. CI: recent MI; arrhythmia; glaucoma. ECG if cardiac risk. Nortriptyline: better tolerated (less anticholinergic). Duloxetine (SNRI): alternative; especially if comorbid depression or anxiety.
"This tablet relaxes the muscle spasm in your back for a short period. I am prescribing it for [5] days only — it is not for long-term use. Do not drive while taking it — it will make you drowsy. Do not drink alcohol while taking it. After [5] days, stop — if the spasm is still severe, come back and we will review."
Diazepam: for acute muscle spasm ONLY; 2–7 days maximum; never for chronic LBP; CD Schedule 4; warn: no driving; no alcohol; dependence risk even short-term. SCA: prescribing diazepam for David without time limit = Tasks fail. Any repeat without review = significant prescribing error. For chronic LBP: amitriptyline or duloxetine preferred to benzodiazepines.
"This tablet works on the pain pathways in your spinal cord — it is not just an antidepressant; it is specifically used for back pain. Take it with food to reduce nausea; that usually settles after a week or two. It takes about 4–6 weeks to feel the full effect. If I need to stop it, we do it gradually over a few weeks — never suddenly."
Duloxetine 30mg OD titrated to 60mg: NICE NG59 specifically endorses for chronic LBP; especially if comorbid depression/anxiety. Start 30mg OD for 1 week (nausea); increase to 60mg OD. 4–6 weeks for full effect. Taper over 4 weeks on discontinuation. CI: MAOI; uncontrolled HTN; severe hepatic/renal impairment. Monitor BP; PHQ-9. Alternative to amitriptyline in chronic LBP; better tolerated in patients who cannot take TCAs.
Driving
DVLA: no specific driving restrictions for back pain per se. However: opiate analgesics (codeine; tramadol; morphine) impair driving — patient must not drive if affected; DVLA statutory duty to inform if a condition impairs driving. Diazepam: do not drive while taking (sedation; legal requirement). NSAIDs and amitriptyline at low doses do not usually preclude driving but warn about sedation with TCA initiation. David: can drive if not taking sedating medication and his pain allows safe driving.
"You can drive if you feel able to control the vehicle safely — that is the legal test. But while you are taking the codeine or the diazepam, please do not drive. Let me know if the pain itself is making it unsafe."Work and Income
David has been off work 2 weeks as an office manager. Prolonged sickness absence is independently associated with worse back pain prognosis. Early return to modified duties (working from home; reduced hours; no heavy lifting) is both clinically better and financially important. Fit note (MED3): “may be fit for work” with modifications rather than “unfit for all work.” Statutory Sick Pay; Employment and Support Allowance if prolonged incapacity. Occupational health referral for complex return-to-work.
"Getting back to some work — even part-time from home — is actually one of the best things you can do for your recovery. Can we talk about what a phased return might look like? I can write a letter to your employer if that would help."Carer Role — Wife with MS
David’s back pain has disrupted his ability to care for his wife. This creates a reciprocal burden: his anxiety about her welfare worsens his own pain; his incapacity generates guilt and depression. Carer’s assessment (Care Act 2014): David may be entitled to a carer’s assessment from social services. Emergency care plan for his wife. MS Society and social services involvement. GP must acknowledge this dual burden explicitly: David’s recovery matters for his wife as much as for himself.
"I know you are worried about Sandra as well as your own back. Let’s make sure she is getting the support she needs while you recover — can I refer you both to social services for a carer’s assessment? And the faster we get you better, the sooner you can be back to caring for her."Sleep Disruption
Back pain worsens sleep; poor sleep worsens pain. This bidirectional relationship accelerates chronification. Night pain (waking in the second half of the night) is also a red flag for inflammatory back pain or malignancy — ask specifically. For mechanical LBP: amitriptyline 10mg OD at night addresses both pain and sleep. Sleep hygiene advice: consistent sleep time; cool dark room; avoid screen use before bed; avoid caffeine after 2pm; gentle stretching before bed (reduces muscle tension).
"Have you been sleeping? Back pain and sleep have a difficult relationship — the pain interrupts sleep, and poor sleep makes the pain harder to bear. The low-dose tablet at night I am prescribing for chronic pain also helps with sleep — that is part of why I am choosing that one."Relationship and Intimacy
Back pain significantly affects sexual activity and intimacy. Pain; fear of worsening; reduced mobility; and psychological distress combine to impair sexual function. This is rarely raised spontaneously but is highly relevant to quality of life. The GP who raises it first — briefly and sensitively — normalises the concern and opens a conversation. For sciatica specifically: sexual positions that avoid lumbar flexion and rotation are more comfortable; physiotherapist can advise. This is a domain that patients carry alone unless invited to discuss it.
"There is one more thing I want to ask about — people often find that back pain affects their relationship and intimacy with their partner, but feel embarrassed to mention it. Has that been a concern? There is practical advice we can give about positions and movement that make things more comfortable."Exercise Identity and Mental Wellbeing
If David was previously physically active (common in office workers who gym or play sport), back pain causes loss of exercise capacity — which is a significant source of psychological distress. Exercise is also a mental health intervention (depression; anxiety); losing it worsens both pain and mood. The prescription of specific permitted exercise (swimming; walking; Pilates) replaces the lost activity with a medically appropriate alternative that also treats the back pain. This maintains identity and mental wellbeing alongside physical recovery.
"I know being limited physically is really frustrating — especially if you are normally active. What I can offer you is that there are specific types of exercise that are actually good for your back right now — swimming; walking; and a specific Pilates class. This is not a ban on exercise; it is a redirection."Today — NSAIDs; physiotherapy referral; fit note; cauda equina safety-net; exercise advice
Naproxen 500mg BD + omeprazole 20mg OD prescribed. Physiotherapy (MSK) referred today. Fit note (MED3): “may be fit for work” with modifications (home working; no heavy lifting; ergonomic adjustments). Cauda equina safety-net given and documented. Exercise prescription: graduated walking from today. 6–8 week review booked. If acute muscle spasm component: diazepam 2mg TDS for 5 days with explicit time limit documented.
2 Weeks — Telephone review if needed; pain control; NSAID review
Telephone review if David requests: is pain controlled? Is he able to engage with physiotherapy? Are NSAIDs causing GI symptoms? If not tolerating naproxen: switch to etoricoxib 60mg OD + omeprazole. If pain inadequate with NSAIDs: add codeine 30mg PRN for 2 weeks. Review fit note if further sickness absence needed. Encourage return to work if not already returned.
6–8 Weeks — Main review: response to treatment; consider MRI
Face-to-face review. Progress: is David better? Pain scores; functional improvement; physiotherapy attendance; return to work. Neurological review: any change in power; reflexes; sensation. If significantly improved: continue; discharge from GP follow-up; advise on prevention. If not significantly improved: MRI lumbar spine; consider orthopaedic/neurosurgery referral (if MRI shows operable lesion and patient is surgical candidate). If high yellow flag burden: NHS Talking Therapies/CBT referral; consider pain management programme.
12 Weeks — Chronic LBP threshold: multidisciplinary approach
If pain persists at 12 weeks: chronic LBP phase. Pain management programme referral; amitriptyline 10mg OD at night (titrate); or duloxetine 30mg OD titrated to 60mg. PHQ-9 for depression. Consider social prescribing; exercise on prescription. Review MRI results if arranged. Orthopaedic review if MRI shows surgical lesion. Carer’s assessment for wife if not already arranged.
12+ months — Annual review for chronic LBP
Annual review if chronic LBP established. PHQ-9; GAD-7. Review current medication (aim to reduce and stop NSAIDs; review opioid need; review TCA/SNRI dose). Long-term exercise adherence. Occupational review — is David back at full work capacity? Carer capacity for wife with MS. Assess for axial SpA if not previously excluded (HLA-B27; CRP — do not miss a treatable inflammatory cause in prolonged LBP).
PACE monitoring mnemonic for back pain
Pain: VAS/NRS score at every review — is it improving? Activity: what can David do now vs last time? Walking; working; caring for wife. Cauda equina: re-screen at every review (ask; document). Emotion: PHQ-9 and GAD-7 if chronic (>12 weeks) or yellow flag burden high.

- Prescribing gabapentinoids for non-specific LBP — NICE NG59: not recommended; most common SCA prescribing error
- Ordering MRI at 3 weeks without red flags or progressive deficit — not indicated; does not change management
- Validating rest without challenging it — reinforces fear avoidance; rest is harmful for LBP
- Not addressing the fear of surgery specifically — David’s primary concern; leaving it unaddressed = missed Relating to Others mark
- Issuing sick note “unfit for all work” without considering modified duties for an office worker
- Red flags screened; cauda equina documented as absent
- Neurological exam: SLR; power; reflexes; sensation
- NSAIDs first-line (NOT gabapentinoids; NOT paracetamol alone)
- MRI not ordered; specific reason given with 6–8 week plan
- Physiotherapy referral today
- Yellow flags identified; fear avoidance challenged
- Fit note: modified duties; not “unfit for all work”
- Fear of surgery addressed with specific evidence (95% do not need surgery)
- Rest challenged compassionately — with explanation
- MRI redirect: validated then redirected with evidence
- Carer context acknowledged; wife’s support discussed
- Cauda equina safety-net given clearly and specifically
Who you are
David Williams, 42, office manager working from home. Back pain started 3 weeks ago after lifting a box in the garage. Pain goes down the left leg to the big toe and the top of the foot. You have been resting completely for 2 weeks — you are genuinely afraid that movement will make things worse. You had a similar episode 2 years ago that resolved completely with physiotherapy over 4 weeks. You are married to Sandra, 41, who has MS and relies on you for significant daily care (dressing; meal preparation; medications). This worries you enormously.
Hidden agenda — disclose if GP creates space
Fear of surgery (disclose if GP addresses it specifically): “I am really worried this is going to end up needing surgery. My colleague had a disc problem and ended up having an operation. Is that where this is heading?” Respond well if GP gives 95% statistic: “95%? OK, that is much more reassuring than I thought.”
Carer worry (disclose if GP asks about home situation): “The thing is, I am Sandra’s main carer. She has MS and she depends on me. I can’t be like this for months. She isn’t coping that well without me being able to do things properly.” Respond well if GP offers carer’s assessment referral.
Work deadline (raise if GP asks about work): “I have a big project deadline in 6 weeks. I have been worried about how I am going to manage.” Respond well if GP offers fit note with modified duties + return to work plan.
Responses to key conversations
- On rest challenge: initially resistant: “But surely if it is hurting, I should rest it?” — respond well if GP explains the rationale specifically: “I hadn’t thought of it that way. So the resting is actually working against me?”
- On MRI decline: initially disappointed: “But I want to know what is actually in there.” — respond well if GP explains the 30–40% incidental finding statistic and offers specific 6–8 week plan: “OK, I can live with that if there is a clear plan.”
- On physio referral: initially sceptical (tried it before, took 4 weeks): “I had physio last time — how do I know it will work this time?” — respond well if GP references previous success: “Oh — you’re right, I did get better last time. OK.”
- On cauda equina safety-net: becomes attentive: “So if I get numbness there I should go to A&E — not call the surgery?” — confirm: “Exactly right. A&E immediately.”
Clinical details
- Age 42; 3 weeks LBP; radiation to left leg (L5 distribution: big toe; dorsum foot)
- Positive SLR 45° left (pain reproduced in L5 distribution); no crossed SLR
- Neurology: EHL power 4+/5; sensation dorsum foot mildly reduced; ankle jerk present; knee jerk present
- No saddle numbness; bladder and bowel normal (must ask; document as absent)
- No red flags: no weight loss; no fever; no malignancy history; no steroid use
- PHQ-9: approximately 7–8 (mild depression; sleep disturbed; carer burden; occupational stress)
- Previous episode: 2 years ago; resolved completely with 4 weeks physiotherapy
Resolution: David accepts the plan if: the MRI decline is explained with specific evidence (not just guidelines); a clear conditional MRI plan at 6–8 weeks is offered; the fear of surgery is addressed with the 95% statistic; the physio referral is made today; and the cauda equina safety-net is given specifically. He leaves saying: “OK — I hadn’t realised that moving was actually the treatment. I thought I was protecting it. I’ll try the walking today.”
- Saddle numbness + bladder/bowel change → CES
- Bilateral progressive leg weakness
- Aortic dissection (sudden; tearing; CV risk)
- Epidural abscess (fever + progressive neurology)
- Bilious — [irrelevant; ignore this — clinical notes only]
- Age >50 + weight loss + cancer history
- Fever + immunocompromised (discitis)
- Trauma + osteoporosis (compression fracture)
- Progressive neurological deficit
- Thoracic pain (not lumbar)
- Non-specific LBP: NSAIDs; exercise; physio
- Sciatica <6 weeks: NSAIDs; physio; MRI at 6–8w if not improving
- Axial SpA suspected: NSAIDs; HLA-B27; CRP; rheumatology
| PACE | Parameter | Timing | Action |
|---|---|---|---|
| P — Pain | VAS/NRS pain score; leg pain vs back pain | Every review | Not improving at 6–8 weeks: MRI; orthopaedic. Not improving at 12 weeks: pain clinic; amitriptyline/duloxetine |
| A — Activity | Walking; work capacity; carer capacity | Every review | Not returning to activity: review yellow flags; NHS Talking Therapies/CBT; occupational health |
| C — Cauda equina | Saddle numbness; bladder; bowel; bilateral weakness | Every review; every consultation | New CES features: 999 / same-day A&E; emergency MRI. Document asked at every visit |
| E — Emotion | PHQ-9; GAD-7; fear avoidance; catastrophising | 12 weeks if chronic; any time if high yellow flag burden | PHQ-9 ≥10: depression management (sertraline; NHS Talking Therapies). High fear avoidance: CBT; PMP |
