Common symptoms
Headache: when to rest, and when to get help
A practical guide to common triggers, simple next steps and warning signs you should not ignore.
Start with the warning signs
Most headaches are not dangerous, but a new or unusual headache deserves attention. The emergency signs above are reasons to act immediately.
If there are no warning signs
Try drinking water, eating regularly, resting when unwell and taking breaks from screens. Avoid alcohol. Ask a pharmacist about suitable pain relief rather than assuming a medicine is safe for everyone.
Arrange medical advice
See a clinician if headaches recur, worsen or do not improve. Get urgent advice for headache with vomiting or eye problems, or one brought on by exercise or coughing.
Make a useful headache diary
Write down when it begins, how it feels, other symptoms, and medicines taken. Bring this record to your appointment. It can help you describe a pattern without trying to diagnose yourself.
