Hi there,
I went through similair issues. I as well had 2 fistualas and an abcess. Talk too your GI about going on Imuran (Azoprine) something lioke that I went on that for some time and a good dose of antibiotics can't remember the 2 and this totaly got rid of my fistulas as well I had my abcess drianed prior to this and it never came back. I am currrently on 3 mg of Entocort a day great drug.
Hope for the best for ya keep your head up. I know I have been there and now have been in remission for 2 years. I am a 34 year old male from Canada.
