I have been having stomach trouble for seven months, I ran upper and lower scopes, abdominal ct scan, 4 stool.specimens, stomach emptying test, blood test, urine test and heart test. Doctor did not find much except gastritis, slow stomach emptying.I still have alot of gas, pain , bloating. Ct scan states I have severe degenerative disease of the back. I take nexium and 300 mg of Zantac nd xanax. I am not sure if I should go back and see my gastro doctor. My stomach always feels tight
