While no headache is pleasant, cluster headaches can be particularly uncomfortable. Sufferers liken the sensation to a hot poker being stuck in their eyes, and may even feel like their eyes are being shoved out of their sockets.
Cluster headaches get their name because they occur in a cyclical pattern. The cluster of headaches may last for weeks or months, with remission periods in between. They are also called “suicide headaches,” because they can drive sufferers to despair.
