What is Headache?

Headache is one of the most common symptoms, experienced by most people from time to time. There are many types; tension headache causes a feeling of pressure around the head, while migraine is throbbing and often on one side and may be accompanied by nausea and light sensitivity.

Most headaches are managed with simple care and lifestyle modifications, but some patterns warrant medical attention.

Possible causes

  • Stress and emotional tension.
  • Poor sleep or irregular sleep schedules.
  • Dehydration and skipping meals.
  • Eye strain or prolonged screen time.
  • Certain food triggers or weather changes in people with migraines.

These are common general causes; identifying the exact pattern requires medical evaluation.

When to see a doctor

Consult your doctor if:

  • Headaches recur or increase in frequency and severity.
  • They do not respond to usual care or affect your sleep and work.

Seek emergency care immediately for sudden, very severe headache ("worst headache of your life"), or headache accompanied by fever and neck stiffness, or blurred vision or speech difficulties, or weakness on one side of the body, or following a head injury.
