i think actually, quite a few ladies, like soybean, do mention fistulas, which possibly start with ulceration or abcess that go right through to rectum. I wonder if sterile wipes would be good, we never know what has spread there from crohns. not sure you're gonna get the help you need with a flippant doc. try another or a GI pref lady, if not try ibd nurse. she might help, but good luck and i hope it heals soon
