Today's question to ponder is, "During the past two weeks has your pain been moving around? How has this affected your belief in the diagnosis?" The answer is yes, undoubtedly, my pain moves around. Some days I have what I call the “point of origin” pain. This is the localized pain around the top right side of my S.I. joint, which doesn’t feel like muscle tightness, per se, but when I stretch, the stretching feels good. This is the first and most persistent pain that I experienced. Other days, there is extreme muscle tightness in the glute medius area. Lately, I haven’t had much problem with the psoas, but today I’ve had a little bit of tightness there. Then some days, I have what feels like joint paint or tenderness right in the center of my back. For whatever reason, that has been the case more often on Mondays. On especially bad weeks, it will have a sudden onset while playing ball with the kids in the afternoon, such as when I bend slightly to catch a ball and that area suddenly erupts in pain, which can last for a couple of days. At other times I have absolutely no pain at all. This moving around of the pain definitely confirms the TMS diagnosis, but my mind wants to know what the exact physiological process is? When I have the point of origin pain, what exactly is happening, to what tendons and/or ligaments, etc.?
