Why headache happens
Tension-type headaches (the most common) come from sustained muscle tension in the neck, scalp and jaw — often triggered by stress, screen time, poor posture or skipped meals. Migraine is a neurological condition with throbbing pain (usually one-sided), nausea, sensitivity to light and sound, sometimes preceded by visual disturbances (aura). Sinus headaches stem from infected or congested sinuses — pressure behind the eyes and cheekbones, worse on bending forward. Cluster headaches are severe one-sided pain around an eye, with tearing and nasal congestion. Dehydration, low blood sugar, caffeine withdrawal and hangovers each have their own mechanisms.
What helps — OTC options & advice
For tension headaches: paracetamol 500-1000 mg works for most. Ibuprofen 400 mg or naproxen 250-500 mg are stronger options if paracetamol isn't enough. For migraine: a triptan like sumatriptan 50-100 mg (prescription) taken at the first sign of pain is the gold standard — over-the-counter combinations of paracetamol + caffeine + aspirin (Saridon, Vasograin) help mild attacks. Anti-nausea tablets like domperidone or ondansetron help if vomiting is part of the picture. For sinus headaches: a combination cold tablet with phenylephrine plus paracetamol (Sinarest, D-Cold Total) tackles both the congestion and the pain. Crucially: don't use any painkiller more than 2-3 days a week for headaches — that's how chronic medication-overuse headache develops, and it's a hard cycle to break.
