Hi! I started doing yoga 2 months ago in order to keep my body active. I thought it would be good , low-impact exercise. It is even included in the (very short) list my rheumathologist suggested me to try. I have a small, skinny, flexible body. I can stretch a lot and do most postures, and I like the challenge of doing them. The problem is that it started to hurt a lot. My body gets wrecked for two days after every yoga class. Then it subsides. But then another class comes and I go through the cycle again. I have learned that arching my spine backwards puts me into great misery a couple of hours later. But even stretching my spine forward gives me pain. Well, most postures do. I tried doing them less intensely but I can't seem to find a balance between "I'm trying the posture instead of just sitting down" and "It hurts". Maybe I need to change my teacher? She knows I can't do some things but she's very severe sometimes. I do Iyengar Yoga, which is mostly Hatha Yoga with some implements like wooden blocks and belts. Or should I change the exercise and move on to tai chi or gym machines with little weight, for example? And, shouldn't all this pain be psychosomatic??? Why does it hurt??? I have developed a better attitude regarding pain after reading Sarno, I talk with my brain and I try not to pay attention to the moving pains, but I don't want to feel horrible all week just to do some physical activity!!! I'm so confused!
