For the past two weeks, I ve been experiecning constant pain that seem to move from the middle of my back, to under my scapula , right side of my rib cage , then to my lower sternum . It is not often in that order. This pain is constant. Now and then, I feel this pain in my abdomen . The pain I feel under my right scapula, reminds me of what I call, results from a pinched nerve. When I stretch, or change body position, it tends to momentarily subside.
