I had my reversal in August. I didn't have much pain, but when I did it was usually gas. And that eventually went away. The most severe pain I had post-reversal was when I had a partial blockage. THAT was horrible. Watch what you eat, keep a food diary. See what effects you and how. I ove my jpouch. I am happy to be bag free, even though I was happy with a bag, too. Anything but UC is fine by me. Just give it time. LOTS of time. I was blessed to have an easy recovery from my reversal, but I do know that is not the case for everyone. Always remember, this shall pass. Unless of course you have a blockage, at which point, it will require some medical intervention, and THEN it will pass.
Sorry, I am really tired and have resorted to humor for the colon-less. But I do hope everything calms down soon. Gas-X worked a little for me, I know it doesn't work at all for some people....
