About two years ago i suffered a work-related injury. I bent down to
lift some boxes at work and felt a slight tearing in my shoulders. At first, I thought it was a muscle injury. But as time wore on, and as my tests--two mri and two x-rays of neck, back, spine region--revealed nothing I realized it must be something bone-related. At times during the day, i feel something, be it disks in my back or whatever, slipping in and out of place.
