I have had a very mild, intermitent pain or pressure under my right rib for the past couple of days. It has been accompanied by an increase in gas. It is not the "acute attack" as with gallstones, but is in that area, and there is an occassional pain in the back around the same area. Stools have been slightly loose, but otherwise normal. Normal appetite, no fever. Not sure what to think, and I admit to being more paranoid after my hospital visit for an appendicitis that turned out to be gastroentiritis (3 or 4 months ago). Could it be a very small gallstone having a mild reaction, or just simply gas? Also, I had been going to a chiropractor regularly for the past year and have stopped because of insurance problems, so could that be a factor as well? Pain has not seemed to get much worse, just has been on and off for a few days. Stomach ulcer? Again, no acute, sharp pains, more like a muscle ache or pressure. Thanks, any help or advice would be great.
