HI Scott, sorry I should have made that clearer. Am seeing rheumatologist for enteropathic arthritis - for which he is going to get me onto Humira for. I have read some case studies where this has been shown to be effective for fistulas also. So I am hoping the Humira may help on a few fronts that I have going on - arthritis, cuffitis/div. colitis and the fistula. I've tried the treatments you mention above and they have helped me. Only thing I haven't tried yet is antibiotics. I have read mixed reports on the success of these for div/ colitis / cuffitis so I have been reluctant to use them, but am getting desperate now.
