Is the pain during a bowel movement too? If so, I'd be thinking in terms of a fissure. The pain from the stool hitting the fissure causes severe spasms in the sphincters, that can go on for an hour or more after a bowel movement.
I agree that after nearly two months of Humira, you'd expect some sort of positive response, and certainly not feeling worse. But, they can't really move on to the next thing before giving it the three months. Of course, if there is something else going on, like allergic reaction, bone marrow suppression, lupus syndrome, that sort of thing, then you need to stop the Humira.
If biologics fail, then they are pretty much left with pouch removal...
By the way, Solomin is in the Montreal area. You may want to send him a PM. He's had a lot of trouble with his pouch too.
