Cluster headache gets its name because the attacks come in groups. The pain arrives with little, if any, warning and is usually on one side of the head. A tearing or bloodshot eye and a runny nose on the side of the headache may also accompany the pain. Cluster headache, believed to be caused by chemical reactions in the brain, has been described as the most severe and intense of any headache type. Treatment for cluster headache includes prescription medication and oxygen. Click here for more information.
