My "specialist" doctor recently told me I had to quit running and weight lifting because I have degenerative disc disease. What yoga poses should I avoid? Almost overnight, I've lost my ability to comfortably do forward bends, plow/wide-legged plow, and knees to ears. I've already had surgery for a blow disc (L5-S1), but this pain appears when I run (or "power walk as I do now). I also have flat feet. His diagnosis is killing as I derive tremendous pleasure from running. As per the "Posture Presription", I know longer sit in chairs. I only squat or kneel at a desk. When sitting on a couch, I sit in cross legged postion with a lumbar roll. I do a 90 minute yoga session in the a.m., and a 30 minute one in the afternoon. As per the "McKenzie Method", I do cobra/backend every two hours. In other words, I do all I can to improve things. Nevertheless, the pain the area of my traps appears when I walk or run. Thank you.
