Heya people. Made a spur of the moment phone call last might to a local chiropractor, rather than my usual osteopath. Anyway, they could fit me in half hour after the call so I went over. Had the consultation n exam. He basically reckons that my problem isn't my back it's my pelvis, as i suspected all along. Google sacroiliac joint dysfunction. He reckons where my sacrum (bottom of spine) meets the pelvis one sides joint is too loose n the other too tight. This instability in my pelvis means my back has been compensating for it n so meaning the back muscles easily go into spasm n get strained. He wants to be doubly sure with the MRI that nothing's wrong with my back but he doesn't think there will be. So basically he's gotta sort out my pelvis which means grabbing it n moving it about various ways as the two joints are hard to single out to move.
