What is Cluster Headache?

Q: What is the main cause of cluster headaches?

The exact cause of cluster headaches is unknown, but researchers believe they may be linked to the body's abrupt release of histamine or serotonin. Triggers such as alcohol consumption or smoking can also bring on cluster headaches.

Cluster headaches are a succession of brief but excruciatingly painful headaches that occur daily for weeks or months at a time.
They usually appear at the same time every year, such as in the spring or fall.
As a result, cluster headaches are frequently misdiagnosed as allergies or work stress.
During these cycles, the frequency of your migraines may vary from one headache every other day to numerous headaches every day.
Cluster headaches can cause excruciating pain. Cluster headaches are most frequent between the ages of puberty and middle age, but they can strike anyone at any age.

Cluster Headache Causes

The dilatation, or widening, of the blood arteries that feed blood to your brain and face causes cluster headaches.
The trigeminal nerve, which sends feelings from the face to the brain, is compressed by this dilatation.
The cause of this dilatation is uncertain.
Cluster headaches are a rare form of headache. It's a one-sided headache that can include tears, droopy eyelids, and a stuffy nose.
Attacks range from 15 minutes to 3 hours and happen every day or practically every day for weeks or months.
Pain-free periods of at least one month or more are used to separate the attacks.
