Instant remedy for a headache

Headache is a symptom rather than one diagnosis. Dehydration, heat exhaustion, a common cold, COVID-19, allergic rhinitis, chronic sinusitis, anxiety, or dengue fever can present with headache, alongside many other causes. The location, onset, associated symptoms, and recent exposures matter. A quick remedy may reduce discomfort without treating the reason for the pain.

Rest away from bright light and loud noise, take regular sips of water, and eat a light meal if you have skipped food. Relax your jaw and shoulders, adjust your screen position, and take a break from close-up work. A cool or warm compress may be soothing depending on the pattern. If you use pain medicine, follow the label and check with a pharmacist if you have another illness, take regular medicines, or need treatment for a child. Avoid frequent self-treatment without medical advice.

Get emergency help for a sudden severe headache, new weakness, numbness, trouble speaking, confusion, fainting, seizure, vision loss, or a stiff neck with fever. Seek prompt advice for headache with repeated vomiting, severe dehydration, high fever, a rash, recent head injury, or worsening illness after heat exposure. Arrange a clinical review when headaches recur, change pattern, or do not improve with usual measures.

What features of my headache help identify its cause? Which treatment is safe with my current medicines? Should I keep a record of timing, triggers, and associated symptoms?
