There's been a lot of talk about Botox, Botox for the most part is often injected in order to relax painful spasm of muscles (ie. torticollis). It is FDA approved for some forms of migraine headache in order to reduce severity and frequency of headaches. In a study of adults who tend to get chronic migraine headaches, multiple shots of Botox cut down the total number of days they had them alongside other types of headaches (tension). The study also noted that the patients had less migraine days each month, and they reported less days they needed to take off from work.
In another Botox study, about half of the people who took two or more 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. At Pain and Wellness Northwest, we think Botox works for migraine headaches because it blocks chemicals called neurotransmitters that carry pain signals from your brain. Botox is similar to a roadblock in that pathway. It blocks the chemicals before they get to the nerve endings around your head and neck.
