I am experiencing pain in my back on the right side below the shoulder blade, what could be causing it? I have taken Aleve, Advil, Tylenol, and Flexeril along with applying heat to the area and the pain will not go away. Taking a deep breath hurts, sitting hurts, laying down hurts, standing hurts after a short period of time. The pain is constant and stays in the same spot at all times. What could it be and should I be concerned?
