Interesting study on postoperative success rates of knee surgery: http://www.reuters.com/article/2014/08/21/us-psycholog-pain-knee-replacement-idUSKBN0GL23L20140821 Anyone else think this study is basically looking at TMS, in a very roundabout way? I'll share my own experience. Long before I diagnosed and cured my TMS, I had my jaw advanced by a centimeter. My face swelled to the size of a watermelon and the following two weeks were the most painful of my entire life. When I called my surgeon to get a better pain prescription, he mentioned pain of that level is very unusual. My pain went away when the swelling was mostly gone. TMS? Seems quite possible in retrospect.
