My 21 year old son started 7 days ago with vomiting, diarrhea with red blood in it, stomach cramping, fever and chills. Stool sample test came back clear. He still has diarrhea but no blood in the stool. Fever is gone and hasn t vomited but his stomach is very bloated. He has only been eating broth, rice, bananas, and Gatorade. I m at a loss for how to help him. Family doctor started him on gas X and probiotics.
