to symptoms of abd discomfort, belching and reflux. I had an endoscopy of the stomach today and no ulcers or other abnormalities. He did find some nodular areas in the duodenum which he biopsied. So, does this mean it is all "in my head" or that stress is the cause or emotional causes for symptoms. I have a constant discomfort in the left upper quadrant along with what feels like soreness in the middle of my stomach. I am glad I had this test, albeit, reluctantly; I will try to take Prevacid but these darn proton pump inhibitors cause side effects so I keep trying different ones. What do ya all think?
