What you describe, suggests that your pain is of musculoskeletal origin but it could also be due to disease or compression of nerves, as they emerge from the spinal cord or as they course, from back to
front, between your ribs. You may have to
be evaluated by a rheumatologist to get to the bottom of this. Carefully consider your physical activity and whether any of it could have led to back or spine injury that continues to be aggravated on a regular basis, without enough time to heal.
