A cluster headache is a neurological disorder generally characterized by recurrent, severe headaches typically around the eye on one side of the head. Typically, the headaches occur in a cyclical pattern at almost the same time of the year, typically spring or fall and can last for weeks or months, and can be followed by periods of remission. This severe pain may even go to your forehead, temple, nose, cheek, or upper gum on the same side. Other symptoms include scalp tenderness and blood pulsing when felt. As to its duration, cluster headaches may last between 30 to 90 minutes, which is a relatively short time. In fact, they can disappear in as little as 15 minutes or as long as three hours.
