What should you know about mild cluster headache?

Cluster headache commonly causes severe pain around one eye or the temple, sometimes with a red or watery eye, blocked or runny nose, drooping eyelid, or restlessness on the same side. Attacks can arrive in groups over a period, with symptom-free intervals. The word mild may describe pain at the time or a limited pattern, but it does not confirm the diagnosis.

Other headache disorders can resemble this pattern. A clinician considers timing, location, associated eye and nose changes, medicines, and your examination.

Keep a headache diary with the start time, duration, side, intensity, eye or nose symptoms, possible triggers, and any medicine taken. Arrange a GP Consultation for a new, repeated, or unusual pattern. Do not repeatedly increase painkillers without advice; some headaches become harder to control when acute medicines are used too often. Resting in a quiet room may help some people, but prescribed cluster treatments should be used exactly as instructed.

Seek emergency care for a sudden, explosive Headache, new weakness or numbness, confusion, fainting, fever with a stiff neck, or sudden loss of vision. Urgent assessment is also needed for a painful red eye with marked Light Sensitivity or vision change. A new facial pain pattern deserves timely review even when the pain seems manageable.

Ask whether the timing and one-sided features fit cluster headache, whether an eye or neurological examination is needed, which treatment should be used at attack onset, and how often follow-up is appropriate. Bring your diary and a complete medicine list.
