I am not sue if I should go to the emergency room. As I am being treated for Chron s Disease. For over the last 90 hours or so, anything I eat (small amounts of mild food) chicken soup, 1/2 grilled sandwich, pasta salad with chicken, I throw up within an hour or two and I have severe greenish to a yellowish water diarraha. Could I have some type of bacterial or viral infection? Or something else I should be tested for? Or will this probably go away by itself. I have had two blocked intestinal problems that had required surgery. But I am not having the stabbing pain in the lower intestinal area as before, just a constant ache with some burning along the intestines which I am wondering is from all the diarehha.
