Why do doctors think Botox works for migraine headaches?

ANSWER

Doctors think Botox works for migraine headaches because it blocks chemicals called neurotransmitters that carry pain signals from your brain. Botox is like a roadblock in that pathway. It stops the chemicals before they get to the nerve endings around your head and neck.
