Cluster headache
Clutch headache are

A cluster headache is an uncommon type of headache. It is one-sided head pain that may involve tearing of the eyes, a droopy eyelid, and a stuffy nose. Attacks last from 15 minutes to 3 hours, occur daily or almost daily for weeks or months. The attacks are separated by pain-free periods that last at least 1 month or longer.
Cluster headaches
may be confused with other common types of headaches such as migraines,
sinus headache, and tension
headache.
Causes
Doctors do not know exactly what causes
cluster headaches. They seem to be related to the body's sudden release of
histamine (chemical in the body released during an allergic response) or
serotonin (chemical made by nerve cells) in the area of a nerve in the face
called the trigeminal nerve. A problem in a small area at the base of the brain
called the hypothalamus may be involved.
More
men than women are affected. The headaches can occur at any age, but are most
common in the 20s through middle age. They tend to run in families.
