I was diagnosed with Fibromyalgia about 15 years ago. I had all of the typical symptoms. The symptoms were severe for many years and eased a bit for quite some time showng only one or two symptoms at a time, usually the muscle pain being in the forefront. For the past two years it has gradually increased in intensity again, to where I can barely function daily, due to multiple symptoms. I USE A HAND HELD DOUBLE HEAD VIBRATING MACHINE FOR HOURS PER DAY on my muscles. It offers relief during the self treatment for a short period afterward. I am not sure if relief comes from the muscle manipulation or the temporary short-circuit of the pain nerves in the muscle, but relief is real for that moment, on that body part. I have been doing this for years for relief. So there obviously is something to the vibration treatment!
