That is one of the main characteristics of TMS...it occupies your mind, exactly the way OCD would.
Many have come to this forum with a series of symptoms. We feel alone and scared. We've been taught by the system that this is a physical/engineering problem and it's NOT.
My Pain began in my hips....mostly numbness and a deficiency in motion. It Moved to my butt and back when they told me it was a back problem. Over the next 18 months as it moved all over the place I, like everybody else on this forum, learned way more about anatomy then I ever cared to.....and the result was ending up in a chronic pain facility (dumpster)
I don't know why we get TMS, but I have strong opinions on it. I DO know after being pain free since '99 that learning about the body and paying any attention to it whatsoever , makes it worse. The Doubt is part of that fear no matter how I package it.
