What are people's opinions on the tennis ball trick. I suffer with tight pelvic muscles all caused by my stupid brain. Sitting on a tennis ball and rolling on it really feels good. Now some say this is counter productive but some say if it helps do it. Surely if I know the pain is psychological then trying to ease the symptoms can only be beneficial. At the end of the day I feel if I can get some relief it is better than being in pain all day. But I'm confused because I think I beat this last time by doing nothing. Stopped reading books. Stopped going on these forums. Sure it's a rough ride.
