This was a very interesting article written quite well for the beginner reader. There wasn't a lot of information on exactly how botox is given or works, but the information that was there was really excellent from what I could tell and very easy to read-- I have never had the procedure myself. Only problem I found with it was the inaccuracies in depicting a migraine, what happens when you get one, and the stages, as well as how anti-seizure and anti-depressant medication works to prevent migraine attacks-- very outdated information. To me, this is a big issue-- mis-information and outdated information, and one of the biggest reasons I didn't rate this link any higher. There are better links about Botox. I definitely wouldn't have this in the top 3.

There is a lot of misinformation in this article. There are much better sources about Migraine and Botox on the internet.
