Hi, welcome to the forum.
Considering you have Crohn's and you're in so much incredible pain, it could be that you have something else going on.
Did you have a bm during this time?....did the pain get worse or improve after a bm?
Eating would trigger peristalsis and a "download" of stool from the sigmoid into the rectum if there's any in there, but if you're having any continual excruciating pain over and above anything you've ever experienced, it would be best to get it check it out at either a hospital or at the very least to get in to see your GI asap.
Have you checked in at the CD forum on Healingwell? Some there may have more "experience" with what you're asking.
My initial thought would be a either an abscess or a fistula.
Let us know what the outcome is.

My doc's logic.. "TREAT (FROM)BOTH ENDS" worth it !!!
