How Botox for migraine works
Botox for migraine prevention works by blocking the release of certain brain chemicals including the neurotransmitter acetylcholine and by blocking the movement of certain nerves and muscles. A potential reason might be that Botox blocks nerves that send pain messages to your brain and relaxes the muscles so they are less sensitive to pain. To treat chronic migraine, BOTOX® is injected into muscles of the forehead, the side and back of the head, and the neck and shoulders to produce a partial and temporary chemical denervation of the muscle.
