I have fibromyalgia and most of my pain is in my neck and shoulders. FSM completely relieved the pain. The more treatments you do, the longer you get the pain relief. I also have the brainfog of fibro (and menopause) and it helped with that. I think if you are not getting results, it may be that the person giving the treatment is not well trained. I use a lady who actually trains others in how to use it.
