I got this a few weeks ago, and I’ve used it several times during migraines. My migraines feel very hot and burning sometimes, and the coolness really helps. It is a little too cold straight out of the freezer, so I would recommend letting it sit for 10 minutes.
I have found using SAM-e helps with the blues associated with chronic migraine. I like this particular brand.
Sometimes heating or cooling your neck and shoulders can help. I don’t have this exact one, but something similar.
