Cluster headaches are rare when compared to other types of headaches. The pain they produce is severe and tends to recur in the same way each time. They occur in groups, or clusters, and each attack lasts about 1 to 3 hours on average. The frequency of occurrence may range from every other day to multiple times a day. Cluster periods are followed by remissions that may last months or years.
