Hey -- I'm sorry to say that I'm in the same boat too...I've been flaring since 2 weeks before Christmas...actually started around halloween but my GI didn't contact me about my horrific colonscopy till a few weeks before xmas.
Anyways I feel you on the rectal pain...but I'm also having mouth ulcers on the tongue? It's really weird.
Anyways sorry bout my rambling...I get to see my GI again on wednesday (woopdeedoo! lol)
Hope you feel better!
