I am 46 year old female. In January I had the flu (vomiting, diarhrea, chills, low grade fever). Then in February, same symptons. I went to my family practioner who thought I had diverticulosis. He ordered cat scan. It showed I have thickening of colon and mentioned jejuneum. He sent me to gastroenterologist who thought I had Crohn's disease, but performed upper endoscopy and colonsocopy the same day. He no longer thinks I have Crohn's disease. He took biopsies and I don't have the results yet, but he thought the biopsies looked normal. My blood work was also normal. I have to go to the hospital for a small bowel follow through with more pictures. What else can they test for and will the thickening of the colon go away by itself?
