I have been dealing with 'episodes' as I call them for a year now. It all started last year after I had my first experience with general anesthesia. About 3 weeks later I started having upper abdominal pain right under my ribs and across my whole abdomen, nausea, vomiting, diarrhea, headache, weight loss, joint pain and breat tenderness which the last one just started a couple months ago. The 'episodes' last for about a week then symptoms subside for about 2-3 weeks but they always come back. I have lost 22lbs in the past year. Before this started I was 144 and when I went to see a gastroenterologist last month I was 122 and I am 5'7". I have had my gall bladder removed with no help with the 'episodes'. In 2010 I had a partial hysterectomy. I was fine my whole life and never had any of these symptoms until after general anesthesia. I have had lots of blood work, stool sample, CT, upper endoscopy and a colonoscopy and they have all come back fine. When I had my gall bladder removed my surgeon found pancreatic cells on the outside of my duodenum...don't know why they were there.
