I have been experiencing episodes of stomach pain/distended abdomen (located in the center of my abdomen right at or shortly below the end of the breastbone) with pain that often radiates around my entire lower back. This has been going on for about 2-3 years. About 1 and a half years ago I went in finally complaining to my doctor. At that time I had an ultrasound that showed no gall stones, a normal gall bladder test, EGD that showed a potential start to an ulcer and possible GERD. Celiac disease test came back negative as well. At that time I was also started on omneprozole and that seemed to bring some relief for awhile. When symptoms seemed to return, or again increase in severity they did another EGD and did a test for reflux (placed the probe in the esophagus to measure reflux) and they determined only mild reflux and irritation of the esophagus. These episodes are life altering as continuing on with activity is difficult. Often the onset is in the midafternoon to early evening and I find if sit very still it helps. It often doesn t subside until somewhere in the night as I typically don t awake with any pain. Any suggestions would be appreciated. Thank you.
