I don't have much pain with my flareups but I do get kinda of a feeling like there is a brick in my gut. I have urgency where I have to drop what I'm doing and get to the bathroom within 30 seconds. My BMs are pure liquid and become more frequent by the day. After about
a week I start seeing blood and some mucous and have the urge to push even though there is nothing left. I loose weight very quickly and energy level goes down to a -10.
