right...my GI has never once suggested the possibility of me having crohns, though he knows darn well that I have a fistula & have had it since last November! I always planned to ask him about
it, like "Is there a chance I could have Crohn's?", but never did. I don't know why. I guess because the treatments are so similar, barring surgeries. I swear, next time we talk I'm laying it on the line! But honestly, at this point I don't care which it is, UC or Crohns. If I was heading into surgery I would, but right now, what does it matter? They both stink. I suppose if I was going to try Humira, I'd push for a Crohn's dignosis based on the fistula. Just for insurance purposes.
