For the past few years I've experienced very bad upper back and neck pain. My scapulae and trapezius feel like rocks , and make grating, popping, griding noises when I move my shoulders - as if my knots are rubbing up against each other. I have also had odd joint problems in the past year or so which may or may not be related - tendonitis in my feet, a tearing of my LCL for no known reason. What's up?
