question: Male, 49 years old,6 3 290, had appendix removed. I have a a pain in my right side from just under my rib cage down to about my belt line. I slipped and fell onto my back on my deck and I felt it on my way down, almost like I tightened up and something tore. This happened almost 4 months ago. Pain is not consistent, but flares up when I use my abdominal muscles getting up out of bed or off the couch.
