They said I had been dehydrated from the vomiting and diarrhea, Said I also had acute kidney failure and colitis. Mow in evenings when I lay down, I get strong burning pains in my left side up to the center of my chest. Burping. I have tried heat , ice, tagament, peptobismol and tums. . It last several hrs and even drinking water is painful. Who do I need to see?
