I had my gallbladder removed 5 mths ago, at the same time as having my adrenal gland removed. Since then I have suffered with diarrhoea and stomach cramps, and heavy throbbing pain just under my right shoulder. I have been back to my GP and she has referred me back to my surgeon for further tests. He says he thinks the most likely cause is a trapped gallstone in the bile duct. Apparently this is quite a common occurence, and something that is often not picked up during the initial surgery. I suggest anyone having such problems refers themselves back to the doctor for further tests.
