Cluster headache
Cluster headache is a disorder characterized by episodes of severe headaches on one side of the head, typically around the eye and temple, lasting between 15 minutes to three hours. Episodes are often accompanied by eye watering, nasal congestion, drooping eyelids, or swelling around the eye on the affected side. Cluster headaches are unique in their periodicity and regularity: the headaches occur at around the same hour every day during a cluster period, which typically lasts 8–10 weeks a year. Between cluster periods are pain-free intervals without headaches, which last a little less than one year, but some patients can have cluster headaches without remission periods. The disease is considered among the most painful conditions known to medical science.
