Does anyone have this? I have had it on and off for years.. in 2011, I had this in 2011, had my gallbladder removed and even lost lots of weight( didn't need to). Then they did every test--ct of abdomen, endoscopy, colonoscopy, small bowel study , gastric emptying, Hida scan, MRI and nothing showed up. Then I got better, but get this pain which is also accompanied by lower pelvic pain sometimes and diarrhea... I am having an endoscope on Tuesday but feel very scared when I get this... my gastro doctor thinks it is IBS but I feel it may be more than that-I am very calm most of the time. My only real anxiety is about health issues...
