Cluster Headaches
In contrast to migraine, cluster headaches are much more common in men (6:1).
The onset is usually in the mid 20s.
Typical symptoms are a sharp, stabbing unilateral pain around the orbit, or temporal area. It is often associated with lacrimation (tearing of the eye)
The onset is acute and the pain escalates rapidly and may last
from a few minutes to several hours. Each cluster lasts a few weeks.
Most sufferers have two or three clusters per year.
