question: I am getting spasms under my left rib cage in upper abdomen, I also feel a lump in that location, not sure if knot or something else. I am overweight but been working out for over 6 months... also, pain under shoulder blade on left side that is only helped when I bend over and pop something in my shoulder pain subsides for a while till more pressure. I had Hodgkins 18 years ago.. but overall very healthy. I am 41 5'4" and 240lbs
