How it Works
The short answer: we don’t fully know. However, neurotoxin injections are thought to work by blocking the release of certain brain chemicals including acetylcholine and by blocking nerves that send pain messages to the brain as well as relaxing muscles so they are less sensitive to pain.
Treatment & Results
Those migraine suffers who respond to neurotoxin treatment have varied results. Some feel reasonably better quickly and have fewer headaches, while others find their migraine symptoms completely go way. Only patients with chronic migraine are eligible for treatment with neurotoxin injections. Since there are other treatments available to patients with chronic migraines, it is important that patients have an informed discussion of options for treatment with a practitioner experienced in the diagnosis and management of migraine headaches before a decision to use neurotoxin injections is taken.
