Question I have been healed of back pain by reading Dr. Sarno's book, so I believe that TMS is real and that I am prone to suffer from it. My right knee is stiff but not painful and there are no other symptoms. My PCP says it is OA while a DO says a meniscus tear and wants to operate. How can I know if it is physical or TMS? Should I disregard the doctors and just resume full activity?
