I was in a botox study and had the injections four times. It did not help me, but I understand it can help some. Ever since I had the injections, I have had problems with my neck - restricted movement and severe muscle pain. Apparently paralyzing the muscles in the back of my neck triggered spasms in the muscles on the sides of my neck and I still suffer from it almost two years later. My latest neurologist said she would not have put the injections in the neck. I recommend that if you have the injections, avoid the neck.
