I had a Nissen done almost 2 years ago for symptoms that my Dr. convinced me were due to GERD. I had an upper GI series done at the time that showed GERD. Now these same symptoms have returned (excessive burping, gnawing feeling in stomach, nausea with eating, fumes taste in my mouth, constant throat clearing, blurred vision). All these things went away after the surgery and I thought it must have come undone but the Upper GI Series and Barium Swallow showed everything is good. Does anyone know why this could be... could it still be GERD or something else? Dr. is sending me for an abdominal scan now to check out some other things.
