Chronic cluster headache, not intractable

Cluster headache often causes severe pain around one eye or on one side of the head. The same side may have a watery or red eye, blocked or runny nose, facial sweating or restlessness. Attacks can arrive in patterns over a period, with symptom-free intervals varying between people. “Not intractable” describes headache that is not considered unremitting or impossible to treat; it does not mean the pain is mild.

A clinician will ask about attack timing, duration, triggers, eye and nose symptoms, medicines and any change from your usual pattern. Keeping a headache diary can make these details clearer and help distinguish cluster headache from other causes of headache or facial pain.

Arrange a GP Consultation if attacks are new, recurring or not controlled by your current plan. Record when each attack begins, how long it lasts, which side is affected, associated eye or nose changes, possible alcohol exposure and what treatment helped. Use only medicines or oxygen treatments prescribed and explained for you; some ordinary painkillers may not act quickly enough for cluster attacks.

Ask about both an attack plan and prevention between attacks. Avoid known personal triggers during an active cluster period and keep prescribed treatment available as directed.

Seek emergency help for a sudden explosive headache, new weakness or numbness, trouble speaking, fainting, confusion, seizure, fever with a stiff neck, a painful red eye with vision change, or a headache after a significant injury. Seek prompt review when the pattern changes substantially or treatment stops helping.

Ask how your symptoms fit cluster headache, what to use at the first sign of an attack, how prevention will be monitored, and which medicines or triggers to avoid. Discuss whether a neurology referral is appropriate if the diagnosis remains uncertain.
