I have both multiple sclerosis and fibromyalgia (among other things), and I recently started using a power wheelchair. Although I have been doing gentle yoga exercises (basically, breathing and stretching) for the past year, and though I have had a bit of physical therapy, I continue to have pain in my lower back and in the area of what my yoga teacher calls my "sit bones." I'm not sure how much of my pain is from fibro and how much is associated with MS, but I've gotten helpful advice from this board in the past, and since pain is a basic issue in fibro, I thought I'd ask if anybody has any suggestions. I'm kind of limited in what I can take for pain because of side effects that may worsen one or more of my co-existing problems. That's why I've been focusing on exercise. However, in the past week or so, I've noticed that my left leg seems to be stiffer (more resistant to straighrening out) than it used to be, despite the stretching exercises I try to do. Does anybody have any suggestions? --Laura R.M.
