Headache
Screen SNOOP, then treat tension and migraine well — and avoid opioids.
| If you find… | …then |
|---|---|
| Thunderclap (worst ever, peak within 5 min) | SAH — ED now |
| Fever, neck stiffness, rash, confusion | Meningitis — ED now |
| New neuro deficit, seizure, reduced GCS, papilloedema | Intracranial lesion — ED |
| Age > 50, jaw claudication, scalp tenderness, visual symptoms | GCA — ESR/CRP, prednisolone, same-day pathway |
| Pregnant / postpartum | Pre-eclampsia, venous sinus thrombosis |
| Cancer, immunosuppression, worse lying / coughing, morning vomiting | Raised ICP |
SNOOP
- Systemic symptoms / secondary risk factors (cancer, HIV, immunosuppression)
- Neurological signs
- Onset sudden / Older age (> 50 new headache)
- Pattern change / Positional / Papilloedema / Precipitated by Valsalva / Pregnancy
Any SNOOP feature → this is not a primary headache until proven otherwise.
| Investigation | Only if… |
|---|---|
| None | Primary headache |
| ESR/CRP | Suspected GCA |
| BP + urine dip | Pregnant / postpartum |
Management & advice
- Tension-type: simple analgesia, hydration, sleep, posture; avoid overuse
- Migraine: treat early; dark quiet room
- Medication overuse: simple analgesics < 15 days/month, triptans/codeine < 10 days/month
- Headache diary; GP for prophylaxis if frequent
- Avoid opioids for headache
Refer / follow-up
- Red flags → ED
- Frequent migraine / medication overuse → GP
| Drug | Dose | Duration / notes |
|---|---|---|
| Paracetamol | 1 g every 4–6 hours, max 4 g in 24 h (reduce if under 50 kg or liver risk) | As needed |
| Ibuprofen | 400 mg (up to 600 mg) as a single dose, max three times a day | As needed |
| Migraine: sumatriptan | 50 mg (up to 100 mg); may repeat once after 2 h if headache returns (max 300 mg/24 h) | Avoid in cardiovascular disease, uncontrolled hypertension |
| Migraine nausea: metoclopramide | 10 mg up to three times a day | Max 5 days (or prochlorperazine) |
This sounds like a migraine. The examination is normal, which is reassuring. Take the triptan as soon as a migraine starts, with ibuprofen or paracetamol, and try not to use painkillers on more than 2 or 3 days a week, as that can cause more headaches. Call 999 if you get a sudden, severe headache, a stiff neck with fever, or weakness or problems speaking or seeing.
Come back / call 111 — or 999 if severe — if:
- Sudden severe headache, “worst ever”
- Fever with stiff neck, rash or confusion
- Weakness, numbness, problems with speech or vision, fit
- Headache with jaw pain on chewing or scalp tenderness (over 50)
