Same thing happened to me. Turns out I had a recto-vaginal fistula and the leakage was iritating my urethra and giving me UTI symptoms. My problem was that my gyno, GI and Urologist kept saying it was the other's issue to deal with. Luckily it closed on it's own (I'm on remicade).
33 years old. Diagnosed in 2002ish.

Lower Bowel area only, except for the short stint (about 2 weeks) that I had mouth sores. Also have external/anal fistula and anal/vaginal fistula.
