What are Botox injections?

ANSWER

The botulinum toxin is a toxin produced by bacteria that causes temporary muscle paralysis; it is commonly used for cosmetic reasons, such as treating wrinkles. Botox has been FDA approved to prevent chronic migraine headache in adults. The agency defines chronic headache as having a migraine headache 15 or more days per month with headaches lasting four hours a day or longer. To treat chronic headache, Botox is given about every three months as multiple injections around the head and neck.
