Severe Headache Emergency — Warning Signs

How to recognise a dangerous headache — warning signs of stroke, meningitis, and what to do while waiting for help.

Call 112 immediately for any sudden, severe — especially with , stiff neck, confusion, weakness, or vision changes.

Most headaches are harmless. But some are of life-threatening conditions — , meningitis, bleeding in the brain. Knowing the difference and acting quickly can save a life.

Headaches That Are Medical Emergencies

Thunderclap headache

Maximum intensity within 60 seconds — “the worst of my life.” Can indicate subarachnoid haemorrhage (bleeding around the brain). Call 112 immediately.

Headache with fever and stiff neck

Classic warning signs of meningitis. High + severe headache + stiff neck (cannot touch chin to chest) + sensitivity to light. A non-blanching rash confirms the emergency. Call 112 immediately.

Headache with stroke symptoms — FAST test

Face drooping · Arm weakness · Speech slurred · Time to call 112.

Headache after head injury

Worsening headache hours after a blow to the head — possible slow-expanding blood clot. Go to hospital.

First Aid While Waiting for Help

What to do immediately
1
Call 112 first
Make the call before anything else. Describe clearly: sudden onset, severity, any other symptoms.
2
Keep the person still and calm
Help them sit or lie in a comfortable position in a quiet, darkened room.
3
Do not give aspirin
Aspirin thins blood and can worsen bleeding. Give paracetamol only if certain it is not bleeding-related.
4
Monitor breathing and consciousness
If unconscious but breathing, use recovery position. If not breathing, begin CPR.
5
Stay with them
Do not leave the person alone until emergency services arrive.

Clinical guidance from American Red Cross[1] stresses matching home care to symptom severity and seeking urgent review when red-flag signs appear.

Less Urgent — But Still Needing Assessment

  • New headache different from previous ones
  • Headache that wakes from sleep
  • Headache worsening progressively over days
  • New headache in anyone over 50
  • Headache triggered by coughing or straining
  • Headache in someone with cancer or HIV
