I have been using a good mat to perform home exercises prescribed by physical therapy and some from Sara Meeksbook "Walk Tall". For some reason this week i have been in significant pain (back,neck,hips)about 15 min. after I get off the mat. I have some osteoarthritis and severe osteoporosis. I'm wondering if I now have fibromyalgia, too, or is it just a bad spell I'm going through it's very worrisome. I'm 61.
