Cluster Headaches
Cluster headaches are relatively rare, affecting about 1% of the population. They are distinct from migraine and tension-type headaches. Here are some facts about cluster headaches.
- Most cluster headache sufferers are male-about 85%.
- Cluster headaches come in groups or clusters lasting weeks or month.
- The pain is extremely severe but the attack is brief, lasting no more than a hour or two
- The pain centers around one eye, and this eye may be inflamed and watery. There may also be nasal congestion on the affected side of the face.
- These “alarm clock” headaches may strike in the middle of the night, and often occur at about the same time each day during the course of a cluster.
- A history of heavy smoking and drinking is common, and alcohol often triggers attacks.
