Migraines and cluster headaches are vascular headaches, while tension headaches are not. Cluster headaches are called that because they occur more in clusters and then go away. They usually occur in the exact same spot, and the person often experiences unilateral facial sweating and abnormal facial sensation. Cluster headaches are treated with the same medications that are given for migraine headaches. Tension headaches are not vascular headaches. They don't have that pounding nature. There is more of a constant ache, and often the neck or the sides of the head are involved.
By Mayo Clinic Staff. Print. Cluster headaches, which occur in cyclical patterns or clusters, are one of the most painful types of headache. A cluster headache commonly awakens you in the middle of the night with intense pain in or around one eye on one side of your head. Bouts of frequent attacks, known as cluster periods, can last from weeks to months, usually followed by remission periods when the headaches stop. During remission, no headaches occur for months and sometimes even years. Fortunately, cluster headache is rare and not life-threatening. Treatments can make cluster headache attacks shorter and less severe. In addition, medications can reduce the number of cluster headaches.
