You’ve tried everything for your cluster headaches, and you've gotten no relief. Is it time to look into an experimental treatment called neurostimulation?
The basic idea is to use electricity to activate nerve cells, which alters your body’s pain signals, says Joel R. Saper, MD, founder and director of the Michigan Headache & Neurological Institute in Ann Arbor.
Some of the devices that do that are hand-held. For others, you have to get surgery to implant them, usually in your head.
