Foot Pain Algorithm

Safety

Exclude emergencies & can't-miss diagnoses first

Done

Ask about onset, trauma, systemic features, and vascular/neuropathic risk before any further assessment.

Open fracture / dislocation Visible bone, gross deformity, acute trauma → 999 immediately

Acute limb ischaemia 6 Ps: Pain, Pallor, Pulselessness, Paraesthesia, Paralysis, Perishing cold — features may be incomplete and an absent pulse is not required. Sudden limb pain with pallor, coldness, sensory loss, weakness or absent pulses requires immediate vascular assessment. Call 999 if there is threatened limb viability, severe pain, neurological deficit or systemic instability

Necrotising fasciitis Severe, rapidly progressive or disproportionate pain with systemic illness, skin discolouration, bullae, anaesthesia, oedema or rapidly spreading swelling → emergency hospital/surgical assessment (999; NICE NG253). Crepitus may be absent and normal inflammatory markers do not exclude early disease

Septic arthritis Suspect with an acutely painful, restricted and swollen joint, especially with systemic illness or immunosuppression — fever and raised blood tests may be absent. Refer for same-day hospital assessment (ED/acute medical/orthopaedic pathway) and joint aspiration. Do not delay antibiotics in a septic patient while waiting for aspiration or imaging

Diabetic foot emergency Sepsis, severe ischaemia, gangrene or suspected deep soft-tissue/bone infection → immediate hospital referral. Other active diabetic foot problems (new ulcer, blister, skin break, swelling, erythema, colour change, unexplained pain, suspected Charcot) → prompt assessment and diabetic-foot service referral, usually within 1 working day (NICE NG19)

Deep vein thrombosis Distal foot pain alone is not a typical DVT presentation. Assess suspected DVT (unilateral calf swelling/pain) using the two-level Wells score and the local NICE NG158 pathway (DVT likely → proximal leg vein ultrasound within 4 hours, or D-dimer + interim anticoagulation + scan within 24 hours); do not use D-dimer indiscriminately in older people, inpatients, pregnancy or high pre-test probability. Differentials: cellulitis, superficial thrombophlebitis, ruptured Baker's cyst, trauma/haematoma, venous insufficiency, acute limb ischaemia, compartment syndrome

Stress fracture with high-risk site Anterior tibial cortex, femoral neck, navicular, 5th metatarsal (Jones) in athlete — continued activity risks complete fracture → same-day orthopaedic assessment; stop loading (non-weight-bearing) until seen

Achilles rupture Suspected complete rupture → urgent same-day assessment and immobilisation; 999 only if neurovascular compromise, major trauma or unsafe transfer

Compartment syndrome / major trauma Acute compartment syndrome, major trauma, or acute neurological or vascular compromise → 999

Malignancy / Paget's disease Not for every unexplained foot pain — consider with persistent unexplained focal bone pain, night pain, swelling or mass, unexplained fracture, constitutional symptoms, abnormal examination, history of malignancy, or raised ALP/other Paget clues. Imaging and referral route depend on age, site and suspicion: plain X-ray is a useful first test; consider a suspected cancer pathway referral if it suggests bone sarcoma (NICE NG12, updated April 2026). A normal X-ray does not exclude stress fracture, marrow disease or early malignancy — persistent concern needs specialist review or further imaging. Consider myeloma and metastases in older adults

Missed vascular emergencies and necrotising fasciitis carry catastrophic consequences within hours. Acute limb ischaemia needs immediate vascular assessment to save the limb. Untreated septic arthritis rapidly destroys cartilage. Diabetic foot infection is a major cause of non-traumatic amputation; NICE NG19 recommends immediate hospital referral for limb- or life-threatening problems and referral to the multidisciplinary foot service, usually within 1 working day, for other active problems. Stress fractures at high-risk sites (navicular, Jones) progress to complete fracture with permanent disability if loading continues — early orthopaedic input is mandatory.

Diagnose

Structured history — localise and characterise the pain

Done

Use anatomical location + onset + aggravating factors as your primary diagnostic filter. The foot has 6 key zones — establish which first.

Location

Heel (plantar/posterior), midfoot arch, forefoot/metatarsal heads, toes, diffuse — narrows differential immediately

Onset & duration

Acute (trauma, gout, septic arthritis) vs insidious (>6 weeks → plantar fasciitis, stress fracture, Morton's, inflammatory arthritis)

Character

Sharp stabbing (plantar fasciitis, Morton's neuroma), burning (neuropathy), throbbing (gout, infection), aching (structural/mechanical)

Timing

First-step morning pain → plantar fasciitis; post-activity → stress fracture; night pain → gout, neuropathy, malignancy (alarm)

Aggravating/relieving

Weight-bearing worsens most; rest relief supports mechanical cause; NSAIDs dramatically relieve gout & inflammatory arthritis

Radiation

Into toes → Morton's neuroma (3rd–4th webspace), tarsal tunnel; up leg → referred lumbar, DVT, vascular

Associated features

Swelling, erythema, fever, skin changes, nail dystrophy, numbness/tingling, bilateral symptoms

Systemic review

Diabetes, gout history, psoriasis, IBD, recent sore throat/urethritis (reactive arthritis), RA, SLE, medications (fluoroquinolones → tendinopathy)

Red flag symptoms

Weight loss, night sweats, constant night pain, age >50 with no prior diagnosis → screen for malignancy/Paget's

Activity & footwear

Recent increase in training load (stress fracture), occupation (prolonged standing), footwear type and fit

Location alone narrows the differential to 2–3 diagnoses in most cases. Plantar heel pain in a 40–60 year old with first-step pain is most likely plantar fasciitis, but consider alternative causes of heel pain. Asking about morning stiffness lasting >30 minutes and involvement of other joints differentiates inflammatory arthritis (requiring DMARD therapy) from mechanical causes. The fluoroquinolone/tendinopathy link is a commonly missed iatrogenic cause. Bilateral symptoms should always prompt systemic disease screening.

Diagnose

Classify by anatomical zone & likely diagnosis

Done

Match location to the most likely diagnosis. Most foot pain diagnoses are clinical — classification guides investigation and treatment choice.

🟥 Plantar heel

Plantar fasciitis (most common) — first-step pain, worse AM, tender at medial calcaneal tuberosity. Also: Fat pad atrophy (elderly), Calcaneal stress fracture (focal tenderness; squeeze test supportive only), Tarsal tunnel syndrome (burning, tingling medial ankle)

🟧 Posterior heel

Achilles tendinopathy — mid-portion (2–6 cm above insertion) vs insertional. Also: Retrocalcaneal bursitis, Haglund's deformity (prominent posterosuperior calcaneus)

🟨 Midfoot / arch

Tibialis posterior tendinopathy — medial arch pain, flat foot progression, post-menopausal women. Also: Midfoot OA (dorsal osteophytes), Navicular stress fracture, Lisfranc injury (post-trauma — do not miss)

🟩 Forefoot / MTP joints

Morton's neuroma (3rd–4th webspace burning; Mulder's click supportive, not diagnostic). MTP synovitis, plantar plate injury, fat-pad pathology. Metatarsal stress fracture (2nd/3rd shaft, focal tenderness). Freiberg's disease (2nd MTP, adolescents). Sesamoiditis (under 1st MTP)

🟦 Toes

Hallux valgus (1st MTP deviation + bunion). Hallux rigidus (1st MTP stiffness/OA). Hammer/claw toes (deformity + dorsal corn). Ingrown toenail (lateral nail fold infection)

🟪 Diffuse / systemic

Gout (acute 1st MTP, red, swollen — podagra). Psoriatic arthritis (dactylitis, nail changes). Reactive arthritis (asymmetric, post-infection). RA (symmetric MTP synovitis). Peripheral neuropathy (burning bilateral, distal, diabetes/alcohol)

Correct anatomical classification prevents treatment mismatches. Plantar fasciitis and calcaneal stress fracture both present with heel pain but require opposite initial management (exercise vs offloading/imaging). Missing a Lisfranc injury (ligamentous injury between 1st–2nd metatarsals and cuneiforms) leads to chronic midfoot instability and early arthritis — weight-bearing X-rays are essential if suspected after trauma. Inflammatory arthritides (RA, psoriatic, reactive) need early DMARD therapy; delayed diagnosis accelerates joint destruction.

Diagnose

Targeted foot examination — look, feel, move, special tests

Done

Examine weight-bearing and non-weight-bearing. Always check both feet. Examine footwear wear patterns — they reveal gait and loading abnormalities.

Inspection (standing)

Arch height (pes planus / cavus), alignment, swelling, erythema, skin, nails, callus pattern, toe deformities. Observe gait from behind and front

Calcaneal squeeze test

Mediolateral compression of calcaneus — pain supports a calcaneal stress injury but the test is not sensitive or specific enough to exclude it. Escalate according to history, focal tenderness, inability to bear weight and risk factors

Plantar fascia palpation

Characteristic pattern: plantar medial heel pain, worse with initial steps after rest, tenderness at the medial calcaneal tubercle. Pain with passive toe dorsiflexion (Windlass test) may support the diagnosis but a positive test is not required

Achilles tendon

Palpate mid-portion and insertion; assess Thompson's test (calf squeeze — no plantarflexion = complete rupture → urgent same-day assessment and immobilisation; 999 only if neurovascular compromise, major trauma or unsafe transfer); crepitus suggests tendinopathy

MTP joint assessment

Squeeze across metatarsal heads (metatarsalgia, RA synovitis). Mulder's click test for Morton's neuroma (compression + dorsoplantar squeeze — audible click + pain) is supportive but not diagnostic; consider MTP synovitis, metatarsal stress fracture, Freiberg disease, plantar plate injury and fat-pad pathology. Assess 1st MTP range for hallux rigidus

Tarsal tunnel

Tinel's sign: percuss posterior to medial malleolus — tingling in plantar foot distribution may support tarsal tunnel syndrome but is not reliable enough to confirm it — neuropathic symptoms, examination findings and specialist assessment are more important

Neurovascular

Dorsalis pedis + posterior tibial pulses; capillary refill (a normal refill does not exclude peripheral arterial disease); light touch/monofilament sensation (10g Semmes-Weinstein); vibration (128Hz tuning fork). ABPI may be falsely high in diabetes or medial arterial calcification — consider toe pressures or vascular assessment where indicated. In diabetes also assess temperature difference between feet, Charcot features, ulcer depth and probing (where competent), infection based on clinical signs rather than a positive swab, off-loading needs and footwear

Ankle / subtalar

Assess dorsiflexion (normal ≥10° weight-bearing); subtalar inversion/eversion; pain on resisted tibialis posterior (tendinopathy vs tear)

Targeted examination discriminates between diagnoses that history alone cannot. Thompson's test must be performed whenever Achilles rupture is possible — a palpable gap alone has poor sensitivity. Monofilament testing (10g Semmes-Weinstein) is recommended in NICE NG19 for peripheral neuropathy screening in diabetes; missing neuropathy means missing the patient's ulcer risk. Mulder's click supports Morton's neuroma but is not diagnostic — consider other causes of forefoot pain. Always assess the entire kinetic chain — limited ankle dorsiflexion (e.g., tight gastrocnemius) is a primary driver of plantar fasciitis and needs addressing in treatment.

Diagnose

Targeted investigations — investigate selectively, not reflexively

Done

Most mechanical foot pain diagnoses are clinical. Request investigations only when they will change management or rule out serious pathology.

X-ray foot/ankle 1st line

Weight-bearing views (AP + lateral) for: suspected fracture, Lisfranc injury, OA, hallux valgus, Charcot. Not routine for plantar fasciitis — heel spurs correlate poorly with symptoms (common in asymptomatic adults). A normal X-ray does not exclude stress fracture, marrow disease or early malignancy, and a routine foot X-ray is not an adequate cancer investigation

Bloods — gout screen

Measure serum urate in suspected gout. A level below 360 μmol/L during a flare does not exclude gout; repeat at least 2 weeks after the flare has settled if clinical suspicion remains. Hyperuricaemia alone does not confirm gout. If diagnosis is uncertain, consider joint aspiration for crystal analysis. Urea & creatinine; eGFR baseline before urate-lowering therapy

Bloods — inflammatory

CRP, ESR, FBC if: suspected septic arthritis, inflammatory arthritis, or systemic disease. Anti-CCP/RF only where RA is clinically suspected — do not delay rheumatology referral while awaiting results. Do not routinely request HLA-B27; reserve for a compatible axial/peripheral spondyloarthritis presentation where the result may support specialist assessment

Bloods — metabolic

HbA1c + fasting glucose if neuropathy or diabetic foot; calcium, ALP if Paget's suspected (markedly raised ALP); vitamin D if diffuse pain

MRI 2nd line

Suspected: navicular/Jones stress fracture (plain X-ray initially normal), Morton's neuroma if uncertain, tarsal tunnel, osteonecrosis, soft tissue tumour. Access depends on local MSK/orthopaedic pathways (GP direct-access MRI is not always required or available) — refer and give weight-bearing advice promptly rather than waiting for MRI. MRI preferred over CT for bony stress injury

Ultrasound

May be useful for Achilles tendon pathology, plantar fascia or Morton's neuroma when the diagnosis is uncertain — not routinely required for typical clinical presentations; guided injection planning

Joint aspiration

If septic arthritis is suspected, aspiration should be performed urgently in hospital. Do not inject a joint or give intra-articular corticosteroid until infection has been excluded. If gout is uncertain, consider aspiration for crystal analysis. Polarised light microscopy: negatively birefringent urate crystals = gout; positively birefringent = pseudogout

Do NOT routinely order

HLA-B27, RF/anti-CCP or broad blood panels for every foot pain presentation; D-dimer outside the Wells-based DVT pathway; MRI for uncomplicated plantar fasciitis; bone scan (largely superseded by MRI); nerve conduction studies in primary care (refer if tarsal tunnel confirmed clinically)

Over-investigation of plantar heel pain is common and delays treatment. Heel spurs are common on X-ray in asymptomatic adults; requesting routine X-ray creates false causality and unnecessary patient concern. However, plain X-ray weight-bearing views are critical for Lisfranc injury — non-weight-bearing views can miss injuries. MRI is the gold standard for navicular and Jones stress fractures as plain X-rays are often normal early on. Joint aspiration in suspected septic arthritis is both diagnostic and therapeutic and should be done urgently in hospital — do not delay antibiotics in a septic patient while waiting for aspiration or imaging.

Refer

Referral criteria — know when to escalate and to whom

Done

Most foot pain is managed in primary care. Refer early for high-risk diagnoses, failed conservative management, or when specialist intervention is required.

999 Emergency

999 Acute limb ischaemia, open fracture, dislocation or gross deformity, neurovascular compromise, major trauma, necrotising fasciitis with systemic illness, severe sepsis from a foot source, acute compartment syndrome, acute neurological or vascular compromise, complete Achilles rupture with neurovascular compromise

Same-day urgent

Same-day Suspected septic arthritis (acutely painful, restricted, swollen joint — fever may be absent) → same-day hospital assessment (ED/acute medical/orthopaedic pathway) and aspiration. Diabetic foot with sepsis, severe ischaemia, gangrene or suspected deep soft-tissue/bone infection → immediate hospital referral; other active diabetic foot problems → multidisciplinary foot service, usually within 1 working day (NICE NG19). Suspected DVT → two-level Wells (NICE NG158): likely → proximal leg vein ultrasound within 4 hours, or D-dimer + interim anticoagulation + scan within 24 hours. Suspected complete Achilles rupture → same-day assessment + immobilisation. Suspected high-risk stress fracture or Lisfranc injury → same-day orthopaedic/fracture assessment. Suspected Charcot foot → multidisciplinary foot service within 1 working day, non-weight-bearing until assessed (NICE NG19). New inflammatory arthritis with persistent synovitis → urgent rheumatology

Suspected cancer

NICE NG12 Not for every unexplained foot pain — consider for persistent unexplained focal bone pain, night pain, swelling/mass, unexplained fracture, constitutional symptoms, abnormal examination, history of malignancy or raised ALP; route depends on age, site and suspicion. Adults: X-ray suggesting bone sarcoma → consider a suspected cancer pathway referral; a normal X-ray does not exclude early malignancy — persistent concern needs specialist review or further imaging. Children and young people: unexplained bone swelling or pain → consider a very urgent direct-access X-ray (within 48 hours); X-ray suggesting bone sarcoma → consider a very urgent specialist referral (within 48 hours). Adults: unexplained soft-tissue lump increasing in size → consider an urgent direct-access ultrasound (within 2 weeks); ultrasound suggesting soft tissue sarcoma, or uncertain findings with persisting concern → consider a suspected cancer pathway referral. Children and young people: unexplained lump increasing in size → consider a very urgent direct-access ultrasound (within 48 hours) (NICE NG12, updated April 2026)

Urgent routine (2–4 wks)

Lower-risk stress fractures not settling with protected weight-bearing → orthopaedics/MSK (high-risk sites — navicular, Jones, 5th metatarsal — and Lisfranc are same-day; Charcot within 1 working day, above). Acute gout not responding to first-line therapy → rheumatology

Primary care / rehabilitation

Typical plantar fasciitis, uncomplicated tendinopathy, stable hallux valgus/rigidus, Morton's neuroma, uncomplicated metatarsalgia, uncomplicated gout after appropriate diagnostic assessment

Routine orthopaedics / MSK

Hallux valgus/rigidus affecting quality of life and failed conservative management (6 months). Plantar fasciitis failed 6-month conservative treatment. Morton's neuroma failing conservative measures. Hammer/claw toes with pain/ulceration. Tarsal tunnel syndrome confirmed clinically

Podiatry Primary Care

Diabetic foot annual review + any foot concern in diabetics. Nail pathology (ingrown nails, onychomycosis resistant to treatment). Orthotics assessment for plantar fasciitis, tibialis posterior dysfunction, metatarsalgia. Callus/corn management. Verruca pedis not resolving

Physiotherapy

Plantar fasciitis, Achilles tendinopathy (progressive tendon-loading rehabilitation), tibialis posterior tendinopathy, post-fracture rehabilitation. Self-refer where available or GP refer

Rheumatology

New inflammatory arthritis (RA, psoriatic, reactive), recurrent gout with renal impairment, suspected crystal arthropathy needing DMARD decision, seronegative arthropathy

Vascular surgery

Suspected peripheral arterial disease, non-healing ulcer, rest pain or tissue loss — emergency for acute or critical ischaemia, gangrene, suspected deep infection/osteomyelitis or rapidly progressive tissue loss. ABPI <0.8 alone does not define critical limb ischaemia, and ABPI may be unreliable in diabetes — consider toe pressures

The diabetic foot pathway is set out in NICE NG19 — referral within 1 working day to the multidisciplinary foot care service for any active diabetic foot problem, and immediate acute referral if limb- or life-threatening (NICE NG19). Delayed referral is the most common preventable cause of lower limb amputation. Jones fractures (5th metatarsal base, zone 2) have a high non-union rate with conservative management — early orthopaedic input determines whether surgical fixation is needed, particularly in athletes. Early podiatry and foot-protection input for people with diabetes at increased risk is part of NICE NG19.

Treat

Condition-specific treatment — structured by diagnosis

Done

Treatment is diagnosis-specific. Address the four most common diagnoses in primary care below. Always start with conservative measures before escalation.

① Plantar Fasciitis (most common)

Step 1Load management + analgesia: Education; reduce high-impact activity (not rest). Consider short-term analgesia only where clinically appropriate — simple analgesics are not necessarily effective for chronic plantar fasciitis. Silicone heel cup / supportive cushioned footwear

Step 2Physiotherapy — stretching programme: Plantar fascia stretch (towel toe-curls) and calf stretches (Achilles/gastrocnemius) regularly, including before the first steps in the morning. Night splint if early morning pain prominent. Progressive exercise programme; refer to physiotherapy or podiatry if symptoms persist

Step 3Orthotics & podiatry: Custom semi-rigid orthotics for pronation/pes planus. Podiatry referral for taping, assessment. Consider if failed step 2 at 6 weeks

Step 4Corticosteroid injection (persistent symptoms despite conservative care; specialist-led or ultrasound-guided preferred): do not inject routinely — confirm the diagnosis and consider alternative causes of heel pain first. Discuss uncertain, short-term benefit and risks including plantar fascia rupture and fat-pad atrophy

Step 5Specialist referral at 6 months if failed all above: after discussion of uncertain or short-term benefit and treatment risks, extracorporeal shockwave therapy (ESWT — NICE HTG200, formerly IPG311: no major safety concerns but efficacy evidence inconsistent — special arrangements for consent/audit), platelet-rich plasma, or surgical plantar fasciotomy (last resort)

② Acute Gout

NICE NG219: offer an NSAID, colchicine or a short course of oral corticosteroid, chosen according to renal function, cardiovascular/GI risk, drug interactions and patient preference. Check doses in the SPC and your local formulary.

Option — no renal, CV or GI contraindication

Naproxen NSAID

Lowest effective dose for the shortest time (e.g. 500 mg BD with food) after assessing renal function, BP, heart failure, ulcer history, anticoagulation and age. Add PPI where indicated. Do not stop low-dose aspirin taken for cardiovascular indications

Option — after renal and interaction check

Colchicine 1st line alt.

Dose only per the current SPC and local formulary after checking renal function and interacting medicines — high-dose regimens carry significant toxicity. Particular caution with eGFR impairment, macrolides, ciclosporin, statins, strong CYP3A4/P-glycoprotein inhibitors, frailty and older age. Watch for diarrhoea/GI upset

Option — short oral course

Prednisolone Oral steroid

30–35 mg once daily for 3–5 days, then stop (no taper needed for short course). Check HbA1c / blood glucose if diabetic

Urate-lowering therapy

Usually lifelong. Start 2–4 weeks after a flare has settled, or during a flare if attacks are frequent and the patient agrees, with anti-inflammatory treatment (NICE NG219). Allopurinol or febuxostat are first-line (allopurinol preferred in major cardiovascular disease). Start allopurinol low and titrate according to monthly serum urate to target <360 μmol/L for most people; consider <300 μmol/L for tophi, chronic gouty arthritis or ongoing frequent flares despite <360 μmol/L. Continue colchicine prophylaxis while the urate target is being reached, not simply for a fixed 6 months

Monitoring on allopurinol

Check renal function; consider LFTs as clinically indicated (routine FBC/LFT not universally required for uncomplicated allopurinol). Monthly serum urate during titration, then annually once at target. Allopurinol hypersensitivity: stop and seek urgent assessment for rash, fever, facial oedema, mucosal involvement, lymphadenopathy or systemic illness

③ Achilles Tendinopathy

Step 1Activity modification: Reduce aggravating load (not complete rest); avoid hills/barefoot. Heel raise may offload the Achilles. Routine naproxen may not be appropriate for chronic tendinopathy — short-term analgesia only if clinically appropriate

Step 2Progressive calf and tendon-loading rehabilitation: Physiotherapy referral for a supervised, graded programme. Eccentric-only (Alfredson) protocols are one option but are not suitable for every patient, particularly acute insertional disease or partial tear

Step 3Persistent symptoms: Sports/orthopaedic referral — options such as ESWT, PRP or off-label GTN patches have limited evidence and are specialist decisions. Consider imaging or specialist referral sooner for suspected rupture, partial tear, marked weakness or severe insertional disease

⚠ Do NOT inject corticosteroid into or around the Achilles tendon — risk of tendon rupture. Peritendinous steroid injection is contraindicated in Achilles tendinopathy.

④ Inflammatory Arthritis (new presentation)

Acute analgesia

NSAIDs are symptomatic treatment only while specialist diagnosis and DMARD initiation are arranged — not adequate treatment for suspected RA or psoriatic arthritis. Assess renal function, BP, heart failure, ulcer history, anticoagulation and age first; lowest effective dose with gastroprotection where indicated. Do not start DMARD without specialist input

RA suspected

Anti-CCP + RF; refer urgently to rheumatology — NICE NG100 recommends urgent referral for suspected persistent synovitis, especially with small-joint involvement or more than one joint — follow the local referral service timeframe; do not wait for blood results. Early DMARD (methotrexate ± hydroxychloroquine) started by specialist

Psoriatic arthritis

Refer rheumatology ± dermatology. NSAIDs for symptom control only. DMARDs (methotrexate) needed if persistent — specialist decision

Reactive arthritis

Take a sexual history and arrange appropriate STI testing where relevant — urine culture alone is not sufficient. Treat underlying infection if active. NSAIDs. Usually self-limiting; a minority become chronic — rheumatology if persistent >3 months

Next steps: see Plantar fasciitis · Gout · Morton's neuroma · Peripheral arterial disease · Achilles tendinopathy

Progressive tendon-loading rehabilitation is the mainstay of Achilles tendinopathy treatment. The Achilles tendon has poor vascularity; corticosteroid injection causes collagen necrosis and dramatically increases rupture risk — this is a firm contraindication. For gout, starting allopurinol during an acute attack precipitates a further attack by mobilising urate deposits; NICE NG219 advises starting urate-lowering therapy 2–4 weeks after the flare settles (sooner if flares are frequent). Flare prophylaxis while the urate target is being reached reduces flares during urate-lowering therapy initiation; urate-lowering therapy is usually lifelong. For RA, every week of delay to DMARD therapy correlates with measurable joint erosion progression — urgent rheumatology referral is not optional.

Lifestyle

Non-pharmacological interventions — lifestyle IS treatment

Done

Lifestyle modifications are primary treatment for most foot pain conditions, not adjuncts. Give individualised, specific advice.

Weight management Encourage weight management where clinically appropriate to reduce load through the foot; refer to weight management services / NHS Diabetes Prevention Programme if appropriate

Appropriate footwear Supportive shoes with cushioned heel, wide toe box, and rigid midfoot. Avoid flat flip-flops, high heels, and worn-out trainers. Replace footwear when worn out

Stretching programme — calf & plantar fascia Towel curls, standing calf stretch (gastrocnemius and soleus — separate stretches), stair stretches. Regularly, including before first steps in the morning, as part of a progressive exercise programme

Activity modification — not rest Complete rest is harmful for tendinopathies and plantar fasciitis. Replace high-impact (running, jumping) with low-impact (swimming, cycling) during recovery. Return to running gradually with graded activity, avoiding sudden increases in training load

Dietary modification — gout Focus on weight, alcohol reduction, sugar-sweetened drinks, cardiovascular risk and adherence to urate-lowering therapy. Avoid crash dieting. Dietary changes alone do not replace treat-to-target therapy

Footwear orthotics & self-management Off-the-shelf silicone heel cups (plantar fasciitis) can be bought over the counter. Metatarsal domes for metatarsalgia — position just proximal to MTP heads. Toe spacers for hallux valgus prevention. Custom orthotics via podiatry if significant biomechanical deformity

Smoking cessation Smoking reduces peripheral perfusion and impairs tendon healing. Relevant for all tendinopathies and critical for diabetic foot disease (smoking increases amputation risk in diabetes). Refer to NHS Stop Smoking services; offer NRT/varenicline/cytisinicline (NICE NG209, updated 2025)

Diabetic foot self-care Daily foot inspection (mirror if needed). Moisturise (avoid between toes). Never walk barefoot. Wear properly fitting shoes and specialist diabetic socks. Attend the annual foot risk assessment (NICE NG19). Report any new blister, crack, swelling, redness, discolouration, break in skin or unexplained foot pain promptly (the same day) for assessment via the local diabetic-foot pathway

Footwear change is the single most impactful immediate intervention for most mechanical foot pain. Inappropriate footwear is common at presentation. In gout, lifestyle change supports but does not replace treat-to-target urate-lowering therapy. Foot-care education in diabetes is part of NICE NG19. Embed these as active prescriptions, not general advice.

Safety

Follow-up, monitoring & safety-netting

Done

Always close the consultation with explicit safety-netting. Tell the patient exactly what symptoms should prompt them to return and when to call 999.

1–2 weeks

Acute gout: confirm resolution, check renal function if NSAID/colchicine used, plan urate-lowering therapy. Suspected stress fracture: X-ray result review + orthopaedic referral outcome. New diagnosis: confirm patient understands self-management plan

4–6 weeks

Plantar fasciitis / tendinopathy: assess adherence to stretching programme; if no improvement, progress to step 3 (orthotics, physiotherapy). Inflammatory arthritis: confirm rheumatology referral accepted and appointment booked

3 months

Plantar fasciitis: reassess — most improve. If not, refer to physiotherapy or podiatry; consider injection or ESWT only after discussing uncertain benefit and risks. Gout on allopurinol: monthly serum urate and renal function during titration (LFTs if clinically indicated); increase allopurinol dose if urate >360 μmol/L (or >300 μmol/L if tophi, chronic gouty arthritis or ongoing flares — NICE NG219)

6 months

Failed conservative foot pain: refer orthopaedics/podiatry if not already done. Gout: review serum urate target achieved (<360 μmol/L, or <300 μmol/L if tophi, chronic gouty arthritis or ongoing flares — NICE NG219); continue flare prophylaxis until the urate target is reached, then review; urate-lowering therapy is usually lifelong

Annual

Diabetic foot: annual foot risk assessment with 10 g monofilament testing, pulse check, and inspection for ulceration, deformity, skin and nail changes — NICE NG19 (ABPI only if pulses are reduced or ischaemia is suspected). Gout: serum urate, eGFR, BP annually on allopurinol

Safety-net → 999

999 Sudden severe pain with a pale, cold, numb or weak foot, with or without absent pulses (acute ischaemia). Rapidly spreading redness or swelling, severe pain out of proportion, blistering, skin discolouration or numbness + feeling very unwell (necrotising fasciitis). Foot crushing injury / open fracture

Safety-net → same-day GP

Same-day Any new ulcer, blister, skin break, infection, swelling, colour change, rest pain or rapidly worsening foot pain in a person with diabetes or known peripheral arterial disease → same-day assessment: contact the practice or NHS 111 the same day for the local diabetic-foot/vascular pathway (A&E or 999 if sepsis, critical ischaemia, gangrene, suspected deep infection/osteomyelitis or rapidly progressive tissue loss). Acutely painful, swollen, restricted joint, especially if unwell (septic arthritis — fever may be absent) → same-day hospital assessment (A&E)

Safety-net → routine

Pain not improving after 4–6 weeks of first-line treatment. New swelling / bony deformity not yet imaged. Spreading rash or nail changes alongside joint pain (psoriatic arthritis). New numbness or tingling in feet

Patient information

Provide written information: NHS Choices foot pain page; Arthritis UK gout leaflet; Diabetes UK foot care guide. Self-refer to physiotherapy via NHS self-referral where available locally

Explicit safety-netting is an RCGP SCA marking criterion and a patient safety standard. Diabetic foot safety-netting must be specific: "If you develop any new break in the skin, report it the same day" — vague advice leads to delayed presentations and amputation. Most plantar fasciitis settles with conservative care, so most patients do not need escalation, but 6-month failure should trigger reassessment rather than continued passive management. Serum urate monitoring on allopurinol is frequently omitted in practice — many patients on allopurinol are not at target (urate <360 μmol/L), driving ongoing crystal deposition and silent joint damage. Follow-up is treatment.
