Short answer

Headache without warning signs? Drink some water, do not skip meals and rest if you are ill. Ask a pharmacist which pain medicine suits you, especially with pregnancy, other medicines or health conditions. If it recurs, record the pattern and how many days you take pain medicines; frequent use can perpetuate pain. Sudden extremely severe pain, weakness or confusion: call your local emergency number now. [1][2]

Headache is pain in or around the head. Water, regular meals and suitable pain relief may help ordinary symptoms; some warning signs require emergency care.

What helps first, and when not to wait?

  • For familiar, non-severe headache: drink enough, eat regularly and rest when you have a cold or flu. Ask a pharmacist about suitable pain relief. [1]
  • If pain returns: note onset, duration, location, other symptoms and days using pain medicines. This helps a clinician recognize the pattern. [2]
  • With new warning signs: sudden extremely severe pain, weakness, speech trouble or confusion needs emergency care; do not wait to finish a diary. [1]

Pressing or throbbing pain, nausea and light sensitivity offer clues; a pattern or pain score alone cannot diagnose the cause. [2]

Tension-type headache, migraine and other patterns

Tension-type headache is often bilateral and pressing and is usually not aggravated by everyday activity. Migraine is more often moderate or severe, may throb and may include nausea or sensitivity to light and sound. Cluster headache causes severe one-sided pain around the eye, sometimes with tearing or nasal congestion on the same side. NICE describes these as clinical distinctions for people over 12, not a self-diagnosis checklist. Not every headache related to stress is tension-type headache. [2]

What triggers it, and how often do you take pain medicines?

Too little fluid, missed meals, poor sleep, infection, eyesight problems or stress can play a part; triggers differ between people. If you use acute pain medicines often, note the number of days each month: frequent use over months can itself lead to medication-overuse headache. Discuss the pattern with a clinician rather than abruptly changing prescriptions. A headache by itself does not prove magnesium or another nutrient deficiency. [1][2]

Reasonable first steps

Drink water, eat regularly and rest when you have a cold or flu. Ask a pharmacist whether paracetamol or ibuprofen is appropriate for you and follow its instructions, especially with other medicines, pregnancy or contraindications. Sleeping much more than usual is not necessarily helpful. Relaxation may help when tension worsens pain; it should not obscure warning signs. [1]

Track recurring headaches

Record frequency, duration, severity, associated symptoms, possible triggers and every medicine used for relief. Note any relation to menstruation. NICE suggests recording at least eight weeks when a diary is being used to aid diagnosis; bring it to your appointment. Do not delay assessment of a new alarming symptom to finish a diary. [2]

When to seek care

See a clinician for regular headaches, increasing pain or failure of self-care. Seek prompt assessment for unexplained vomiting, visual or eye symptoms, jaw pain while eating with scalp tenderness, or headache triggered by coughing or exercise. Sudden maximal headache, new weakness, speech difficulty, confusion, seizures, fever with stiff neck or a headache after a recent head injury call for immediate emergency care (112 in the Netherlands, otherwise your local number); do not drive yourself. [1][2]

Frequently asked questions

How is migraine different?

It often disrupts normal activity and can include nausea or light and sound sensitivity. Recurrent attacks deserve assessment; the pattern alone is not proof. [2]

Does every headache call for magnesium?

No, not for every headache. Small studies suggest magnesium may help prevent migraine attacks by reducing how often they occur; this does not show that it stops an attack already underway. The high amounts studied can cause side effects and interact with medicines, so use it for migraine only with clinician supervision. [1] [3]

When is a headache an emergency?

Sudden extremely severe pain or new weakness, speech problems, confusion or fever with a stiff neck requires immediate emergency help (112 in the Netherlands). [1]

Can frequent pain medicines make headaches worse?

Yes. Frequent acute treatments over months can sustain headache; record use days and discuss a plan with a clinician. [2]

What belongs in a headache diary?

Frequency, length, severity, associated symptoms, potential triggers and all pain treatments. Bring the record to your appointment. [2]

Research and sourcesEvidence overview, methods and complete source list

Research context

Water, regular meals, rest during illness and suitable pain relief may help ordinary headache. Track recurring pain and days using pain medicines.

Finding: For non-alarming headache, NHS advises fluids, not skipping meals, rest during illness and suitable pain relief if needed. Sudden extreme pain or new neurological symptoms are not self-care situations.

Self-care for ordinary headache

Evidence: NHS public advice on self-care and warning signs, not an individual effect estimate.

Studied population: People with non-severe headache without warning signs.

Form or context: General self-care and individual pain-medicine choice; no standard drug dose.

Uncertainty: Patterns and causes differ; recurring symptoms may need assessment.

Sources: Headaches

Safety: Sudden extremely severe pain, weakness, confusion, seizure, fever with stiff neck or headache after a recent head injury: call emergency services. Vomiting, vision or jaw symptoms need prompt assessment; ask about painkillers in pregnancy or with other medicines.
