Consider These Triggers of Cluster Headaches: Common Causes
Cluster headaches may be caused by some of the various triggers discussed on these pages:
These headaches differ from other headaches based on the physiologic changes that occur in the brain (involvement of the hypothalamus and trigeminal nerve), symptoms, and course. The reason why people develop these conditions is unknown, but in some cases, there is a genetic component, meaningit may be inherited.
Cluster headaches come on quickly without the prodrome or aura characteristics of migraines. They are often quite severe, sometimes called "suicide headaches" because they are so painful and often debilitating. These headaches manifest by one-sided head pain (sharp, burning, and constant) behind the eye and near the temple. They can be accompanied by redness and watering of the affected eye, swelling around the eye or lid, sometimes a droopy eyelid, a stuffy nose, pupillary changes, ear fullness on the affected side, and sometimes generalized sweating and redness of the skin, nausea and vomiting. Those who have cluster headaches often appear quite restless.
Attacks last from 15 minutes to 3 hours, and they can occur once or repeatedly over the course of a day. This can recur for weeks, months, and (rarely) years. Because an episode occurs in groups, it is called a “cluster” headache. Lying down often causes it to get worse.
