Cluster Headache is a rare but very severe type of headache. It is 6 times more prevalent in men than in women and usually begins in the late twenties or early thirties. The pain is usually centred over one eye, one temple or the forehead. It can spread to a larger area making diagnosis harder. The pain is often described as a “hot poker” penetrating one eye. A number of symptoms may also occur during an attack, including red and watery eyes, blocked or runny nose, flushed or sweating face, constriction of pupils and a drooping or swelling of the eyelid.
Cluster headaches can occur several times a day. In about 80% of people, attacks come in clusters that can last weeks or months and the attacks may disappear for months or even years. This is known as episodic cluster headache.
The remaining 20% of people do not have these pain free intervals and are said to have chronic cluster headache.
