Persistent headache remedies: what to know

A headache that continues may reflect migraine, dehydration, poor sleep, eye strain, infection, medication effects, or another condition. Pain relief can reduce discomfort without explaining why it is happening. Keep a diary of timing, food and drink, sleep, screen use, menstrual or pregnancy status, medicines, and symptoms such as nausea or visual changes.

Brain tumours, including glioblastoma, can cause headache, and brain metastases may do so as well, but persistent headache alone does not establish any of these diagnoses. An examination helps decide whether further testing is appropriate.

Try regular fluids, a calm dark room, gentle neck relaxation, a consistent sleep routine, and breaks from close screen work. Use only a pain medicine that is suitable for you and follow its label or your clinician’s instructions. Check before using a new product if you are pregnant, have kidney or liver disease, have stomach bleeding risk, take blood thinners, or are receiving cancer treatment. Do not stack products with the same ingredient.

Seek urgent care for a sudden extreme headache, new weakness, numbness, confusion, speech trouble, seizure, fainting, repeated vomiting, severe eye pain with vision change, fever with neck stiffness, or a headache after injury. Arrange a timely appointment if it is new, persistent, progressively worse, or repeatedly needs pain medicine.

Ask which cause is most consistent with your pattern, how long to try a recommended remedy, whether your current medicines could contribute, and how to avoid medication-overuse headache. Ask what symptoms mean you should go straight to emergency care.
