Several years ago my husband read Dr. Sarno's book after 6 months of pain. It worked. Then he passed it on to two brothers-in-law. They are no longer in pain. I had no pain at that time; then went through some very challenging times and began to have SI and piriformis pain whenever I stand still or walk slowly. I am very active and can often walk through the pain for 3 miles or more and be pain free at 5 miles. I am convinced this is a psychological syndrome and wish to explore TMS with others here on this forum and in my own readings. I have tried many things -- chiropractic, injections, yoga, massage, pain meds...for three straight years now. I was also convinced it was the post-breast cancer drug I was taking that was causing the problem. Now I am finished with that drug. It's time to stop hurting.
