Cluster headaches are excruciating headaches that are very short in duration and usually felt on one side of the head behind the eyes.
Cluster headaches affect about 1 million people in the United States and are much more common in men. This is the only type of headache that tends to occur at night. The reason that they are called ‘cluster’ headaches is that they tend to occur one to four times per day over a period of several days.
After one cluster of headaches is over, it may be months or even years, before they occur again. Like migraines, cluster headaches are likely to be related to a dilation of the blood vessels in the brain, causing a localized increase in pressure. There are cases where the headaches are caused from neck and muscle problems and mimic these kinds of headaches. Since nerve supply also controls blood vessels, manipulation may have a beneficial effect on this condition.
Each individual’s case is different and requires thorough evaluation before a proper course of chiropractic care can be determined. In most cases of headaches, significant improvement is accomplished through manipulation and massage of exceedingly tight muscles.
