Does research show that Botox works to help migraines?

ANSWER

In a study of adults who get chronic migraine headaches, shots of Botox cut down the total number of days they had them or even other types of headaches. They also had more "crystal-clear" -- pain-free -- days each month, and they reported fewer days off work.

In another study, nearly half the people who took two rounds of Botox shots reported that the number of days they had a headache each month was cut in half. After five rounds of treatment, that increased to about 70% of the people.
