I guess it works for some people but Botox has made my TOS worse. I will never have Botox again. The first time I could only hold my head straight up or resting on my chest. This lated over three weeks before I could control my head. I then had injections a year later in the shoulder. I have had my should taped with KT tape for a year now because I can't hold my shoulder back, it droops. It never stopped the spasms. If you go ahead with Botox, I hope you have better luck.
