What is it?
Botox is a form of a neurotoxin called botulinum toxin, created by the bacteria that causes botulism. When used in tiny doses, it temporarily reduces muscle contractions for approximately 3 months. Botox is usually associated with smoothening of wrinkles, but this procedure is also the only FDA-approved method for chronic migraines (headaches for 15 or more days a month). This procedure is more effective for those who have more frequent headaches.
How does it work?
The Botox is injected 31 times in 7 key muscle areas of the head and neck around the pain fibers involved in headaches. The Botox enters the nerve endings where it blocks the release of chemicals involved in pain transmission, thereby preventing the activation of pain networks in the brain. Each treatment of Botox typically lasts for 10-12 weeks.
What conditions does it treat?
Botox can be used to treat a wide variety of conditions including cervical dystonia, chronic migraine, muscle contractures, and bladder dysfunction.
