Cluster headaches are often described as the worst type of headache, lasting from a few days to months. The pain is usually located on one side of the head. Sometimes this type of headache will last for quite some time and then it may disappear for months, if not years. Thankfully, this type of headache is pretty rare and is often managed by a neurologist. Only about 0.4% of headaches are of this variety.
 
There is a family history of cluster headaches in that 7% of the sufferers will have a relative that has this type of headache. Seasonal association has also been noted. Many people only get them at certain times of the year. There is some thought that the mid portion of the brain, the hypothalamus, is the center of these types of headaches. Often the pain is described as vascular in that this type of headache can actually cause swelling in the blood vessels of the head.
 
Sudden in onset, usually with a small or non-existent warning, the headache sufferer will have a burning or mild discomfort for several minutes before the full onset of the headache. Once the headache starts, there is excruciating pain unlike a migraine. This pain is often more intense. Associated symptoms are a runny or stuffy nose, eye lid swelling or weakness, and a constricted pupil. They can last for a variable amount of time, usually a "cluster" of headaches will occur in a very short time.
 
More men will suffer with this type of headache than women. The Alarm Clock Headache is another name because it will often wake people from their sleep. Also, sleep apnea has also been linked to this disorder. Sleep apnea is more common in men than women also.
