I have trouble with my GI Tract for many years now and have to have a EDG every two years which worked until now. I had one in April of this year that did not work so I had it repeated on the 14th of this month. Concerned because after three days it went back to the same symptoms. Not being able to swallow large amounts of foods, pills, nasty taste in mouth and regurgitation of the mouth and nose. I have severe chest pain especially at night and heart burn. I am wondering if there's anything else that can be done for me. I am also going through a rare form of Breast Cancer at this time.
