My 21 year old son has been experiencing bloody stool, extreme abdominal pain, frequent diarrhea, loss of appetite, extreme back pain, and a weird pain behind his belly button when he extends his abdomen that he states feels as though a ligament is about to pop. He was away at college, and came home for the holidays, and stated the symptoms have gotten progressively worse since the Summer 2015 at its onset... we are looking for a physician, any suggestions....
