Neck has c5/c6 disc protrusion, compressing thecal sac. Burning pain between shoulder blades that never lets up. Surgeon doesn't think neck is damaged enough to cause this pain?? Other joints are cracking and painful within 1 year (back, snapping hip, shifting patella in knee, cracking ankles, cracking wrists). Muscles seem stiff and aggravating joints out of location? Been to RA, Nuerol., Ortho, etc. Are there diseases being missed that cause multiple joints to fail? I can't have 8 surgeries. Have been thru loads of PT. Thanks much for help!
