I was just diagnosed with Crohn's about a month ago after noticing an abscess and having a CT Scan, MRI, and Colonoscopy. The abscess turned into a Fistula and I have not been able to get an appointment with my GI doctor because he was on vacation. His office told me to get one with my primary physician. To treat it she cleaned it out with water and then packed it with gauze that is first treated with Iodine I believe. She also put me on 10mg Pred and an Antibiotic. Is this a usual treatment for a Fistula? I mostly see people talk about Fistulatomys.
