Cluster Headaches

Overview

A cluster headache causes a stabbing pain on one side of your head, often behind or around your eye. Cluster headache attacks occur in cyclical patterns or clusters. You'll experience frequent attacks or cluster periods, which could last for several weeks. After a cluster period, you'll have remission periods when you may not experience any headaches for months or years.

Most people have one or two cluster periods a year, but cluster periods vary in each person. Most people have episodic cluster headaches, in which the cluster periods last from one week to one year, with remission periods lasting months or years. Some people may have chronic cluster headaches, and they may experience cluster periods lasting more than a year with no remission or brief remission periods.
