I was pretty sure all I had was IBS, but now that I may have a fistula I'm beginning to worry. I had a Barium enema done in May, and it came back all normal. I know that things can be missed with that test, but since every other test I've had came back normal my doctor didn't think I needed a Colonoscopy. Of course I'm going to bring all of this up to him now with this new problem.The idea that I even have Crohn's is making me physically ill. I couldn't sleep at all last night. I know a lot of people live with it and manage, but for me it sounds like a death sentance. Is that being silly? My Aunt had a fistula and also has IBS. She has had several colonoscopies and does NOT have Crohn's or IBD. But I know it's a red flag. Feeling so scared about all this!
