I cannot believe you don´t get paid a MRI... what kind of health care system is that??? o_0

@comments: I wouldnt be so harsh on chiropractors (well, except u´r first c, which obviously was a real **** cut-throat). I also keep having back pain, but mostly on low levl, and usually I don´t even notice any more. But once I visited an orthopedist and chiropractor, he talked my into a chiropractic treatment (even though I was actually more concerned that he might screw up my spine, since I also had heard bad stories) and did sth sounding very creepy with my spine, but after that I could discover how great actually u feel with absolutely cero back pain... unfortunately, it didn´t last very long, since there is usually a "good" reason for all that mess, which means that most likely the torso muscles and sinews are in a bad shape... and the best way to deal with poor muscles/sinews is gymnastics and exercises (which might also, but not necessarily, include weight lifting) - on a daily basis.

Maybe - hopefully u can find some helpful exercises for your kind of diagnosis, preferably from an orthopedist, physiotherapist or any other expert... hey, at least some of u´r readers should have some genuine & real expertise on that, right? I´ll keep my fingers crossed, and get well soon!!!
