Cluster Headaches
Signs and Symptoms

Cluster headache attacks may occur nearly every day or several times a day for weeks or months and then disappear for months or even years. Attacks may last from 15 minutes to three hours, and often occur during the night.

There are two kinds of cluster headache: episodic and chronic. Those suffering from episodic cluster headaches have relatively long, pain-free remissions between headaches. Chronic cluster headache sufferers do not have long remissions. If during the past year or longer, you have had only one month or less of relief between headache attacks, you may have chronic cluster headache. About 10 percent of people with cluster headaches are considered chronic sufferers.

Other symptoms, which typically occur on the same side as the pain, include:

  • Red or teary eyes
  • Runny or stuffy nose
  • Facial swelling
