Cluster headaches are a common type of headache more likely to affect men than women. While the gender gap has closed over time, men are still two times more likely to have cluster headaches than women. In this article, we will explain what cluster headaches are, cluster headache causes, and treatments for cluster headache pain.
What Are Cluster Headaches?
Cluster headaches are headaches that occur in clusters or groups. People who experience cluster headaches will have headaches for a period and then experience a period of relief. In some cases, the cycles may repeat. Pain can range from moderate to severe.
There are two types of cluster headaches.
- Episodic cluster headaches are cluster headaches that occur regularly for a period of one week to one year and are followed by a relief period of one month or longer.
- Chronic cluster headaches are cluster headaches that occur regularly for over a year and are followed by a headache-free period that lasts less than a month.
A person who experiences episodic headaches may develop chronic headaches, and the reverse is true as well.
