text: does anyone have any suggestions re: back pain? during my morning stretches and cracks, i locked my arms behind my back (threaded fingers) and pulled upwards and nothing cracked but it felt like it moved, and now i have a really bad pain right between the shoulder blades,   and its making me feel naseaus is this serious????? your best bet is to seek medical attention. if you can't see someone right away, keep a log on the type of pain and any other symptoms that accompany it. these other things may be important to a proper diagnosis.
