Well... I just tried some of the joint mobility exercises that Connie Sol demonstrated on the videos here: http://cfsknowledgecenter.ning.com/group/theexercisegroup I thought I'd do them just to make sure I could, not anticipating any problems, but when I did a couple of the shoulder mobility moves, my left shoulder joint hurt when it got near the furthest extreme of the movement. Connnie says that if anything hurts, then stop. But if you stop when it hurts, how do you ever improve your joint mobility? Anybody got any idea what I should do?
