Besides having TOS, I also have fibromyalgia. When I first started stretching about 15 months ago, I came across this website.http://www.releasefibromyalgia.com/s...romyalgia/#how

This lady says that she cured her fibromyalgia with stretching and it took her about 4 or 5 years, so it's a very slow process. She also thinks that fibromyalgia is basically muscles that are too tight, and I agree with her, in my case anyway. When the muscles get too tight, the nervous system gets out of whack and it causes pain throughout your body.

She also said that she used gentle yoga type stretches and held them for up to 20 minutes at a time. All the stretching I've been doing involves movement, and I never hold a stretch because it flares me up, but it's working for me. So which style of stretching is better? I think you have to experiment and figure out what works best for you. Just because something works for someone else, doesn't mean it's the best way for you. We're all different.
