Cluster headache: Symptoms. Symptoms of a cluster headache include a severe and recurring headache that occurs on one side of the head and is often focused in and around the eye. Cluster headaches generally start suddenly and occur in clusters of episodes that recur over days or weeks. Each episode can last from 15 minutes to several hours.
There's no cure for cluster headaches. The goal of treatment is to decrease the severity of pain, shorten the headache period and prevent the attacks. Because the pain of a cluster headache comes on suddenly and might subside within a short time, cluster headache can be difficult to evaluate and treat, as it requires fast-acting medications. Some types of acute medication can provide some pain relief quickly.
