What it means
Cluster headaches are extremely painful headaches that occur in groups or cycles, often at the same time each day, usually for weeks or months. The pain is typically severe, one-sided, and felt around or behind one eye. It often comes with a red or watering eye, runny nose, or drooping eyelid on the same side as the pain. Attacks usually last 15 minutes to three hours. Unlike migraines, people often feel restless or agitated rather than wanting to lie still. Though not life-threatening, cluster headaches are considered one of the most painful conditions known. Treatment includes oxygen therapy, triptan injections, and preventive medications prescribed by a provider.
