Good day, for the past 4 years or so I have been having some stomach issues. It is a very painful almost unbearable pain that occurs in my abdominal area. I went to a Gastroenterologist and had an endoscopy but that came up clean. Blood results also came up clean. However this must be something! The pain is sometimes so great that I need to go to the E.R. I think that it has a lot to do with gas build up in my abdominal area. If I do not eat at the exact time that I am hungry my stomach fills up with gas and I become full. However if I eat my stomach would still sometimes fill up with gas. Especially during times of high stress/anxiety such as exam time. My most recent attack was two days ago on an airplane. The pain was localized in my top abdominal and was very severe lasting for about 1 hour after I ate some sour candies. Could this be gallstones?

Hi welcome to Chat Doctor forum.  Thanks for calling Chat Doctor. Forum.  You are having the pain in the upper middle part of the stomach. It appears to be the gastric irritation, due to peptic ulcer, or gastric irritation. Or may be gallbladder pain, or pancreas pain.  I advise you to go to the gastroenterologist as a follow-up visit. You may have to get gastrostomy, M.R.I, besides other routine tests for confirmation.  I advise you some diet recommendations as avoid taking spices, junk foods, and oily foods to avoid gastric irritation.  Practice yoga, meditation, reading magazines, and hearing music to avoid stress and anxiety, and hence reflex gastric irritation.  Wishing for a quick and complete recovery.  Best regards.
