Cluster Headaches

Cluster headaches occur in cyclical patterns or clusters and are one of the most painful types of headaches that may last from 15 minutes up to 3 hours long. A cluster headache commonly wakes 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 stops for months, or even years, at a time.


​​Fortunately, treatments can make cluster headache attacks shorter and less severe. In addition, medications can reduce the number of cluster headaches. At Princeton Medical Institute, we are researching various treatments for the prevention of migraines and cluster headaches.
