I am 30 years old and new to all of this and in the middle of a bunch of tests to find a diagnosis. I have hardly ever had any bowel issues until a week and a half ago. In the last week I have had cramping/diarrhea/blood in stool/no fever. At first they thought I had C Diff from antibiotics but that came back negative in a stool sample. I had a positive result of fecal lactoferrin. Dr put me on Flagyl which doesn't seem to be helping. Had a CT scan yesterday which showed thickening of terminal ileum. Radiologist said this could be due to IBD or infection. I now have to have a colonoscopy next week. Does this sound like Crohns to anyone? Im holding out hope that it's just an infection but VERY concerned it's crohns. Can it just show up out of nowhere with no other previous bowel problems? HELP!
