Core rule: examine every child — gait, eye movements, fundi, visual acuity, BP and growth. A new neurological sign or a HeadSmart feature changes the urgency; symptoms that come and go do not exclude a tumour.

0Stop — call 999 now

  • Fever with neck stiffness, photophobia, drowsiness or rash (meningitis) → 999; antibiotic before transfer only if it does not delay it.
  • Sudden severe "worst ever" headache, reduced consciousness, new seizure, acute focal deficit → 999

1Triage by finding

FindingAction
Raised pressureWaking or on waking with vomiting, worse lying or coughing, papilloedema → Same-day
New neuro signAtaxia, nystagmus, squint, head tilt → consider Very urgent 48 h (NG12)
HeadSmartPersistent headache + another symptom, or under 4 → Urgent paediatric
Normal examRecurrent, well between → migraine or tension-type; diary

2Screen

  • Swollen red eyelid or painful eye movements with sinusitis → Same-day
  • Severe hypertension with headache → Same-day paediatrics
  • VP shunt with headache or vomiting → Same-day
  • Several household members with headaches → carbon monoxide

3Assess

☐ BP with the right cuff  ☐ Height, weight, head circumference under 2  ☐ Acuity, eye movements, fundi  ☐ Gait, coordination, cranial nerves  ☐ Analgesic days per month  ☐ Sleep, caffeine, screens, school, mood

Do not: request brain imaging from primary care, or prescribe codeine or aspirin.

4Classify

  • Migraine — attacks with nausea, vomiting, light sensitivity; sleeps; normal between.
  • Tension-type — pressing, mild to moderate, no vomiting.
  • Medication overuse — analgesics on 15 or more days a month.
  • Sinusitis · eye strain — nasal symptoms; worse with reading or screens.
  • Raised pressure — tumour, hydrocephalus, IIH → same-day.
  • Uncertain — diary and review in 2–4 weeks with repeat examination.

5Treat today — doses per BNFC and SPC

  • Migraine: ibuprofen or paracetamol early; dark quiet room; no more than 2–3 days a week.
  • Aged 12–17: consider a nasal triptan if simple analgesia fails; under 12 → specialist.
  • Medication overuse: stop the analgesic; review in 4–8 weeks.
  • Sinusitis: self-care, no routine antibiotic. Vision: optometrist.

6Refer routinely

  • Paediatrics: frequent migraine needing prophylaxis, atypical aura, uncertainty, chronic daily headache.
  • Other: optometrist, CAMHS or school support, dentist.

7Never reassure by

  • Headaches that come and go.
  • An examination that skipped gait, eyes and fundi.
  • A normal examination at a previous visit.
  • "Probably migraine" in a child under 4.
  • Vomiting labelled as a stomach bug when it is on waking.

8Safety-net — say it, then document it

999 “Call 999 for a sudden very severe headache, headache with fever and a stiff neck or a rash that does not fade, if your child is very drowsy or confused, has a fit or new weakness.” Same day “Contact us the same day if headaches wake your child or come on waking with being sick, or there is new double vision, a squint, unsteady walking or a change in behaviour.”

Repeat attendances for the same headache are themselves a flag — re-examine every time.

✓Safe to manage in primary care only if — all five, documented

No red flag or HeadSmart feature Neurology, eyes and fundi examined BP and growth recorded Diagnosis named; diary and review booked Safety-net given to child and parent
