Hi GWEEDEE. Sounds a lot like what I have experienced... I have had pouchitis but this was something different. Turned out to me cuffitis. What worked well for me (quickly) was cortifoam. It comes in a small cylinder can a bit larger that a bic lighter. An applicator is put on top and you fill it with the foam, insert it and squirt it. It hits the cuff area and it really opened things up for me. My cuff is a bit larger than normal according to the scopes... I guess because my surgery was done 30 years ago, the had not quite perfected it. So that area is still vulnerable to UC. The foam seems to fight the inflammation quickly. I also pair it up with Salofalk suppositories.
My symptoms were bloating. A full feeling that I needed to empty but could not. The pressure even effected my bladder and gave me a feeling of urgency to pee. Sort of felt like a lead balloon in my lower abdomen. The urgency was not near the rectum like I normally feel when I need to go.. it was higher up and turned out to be more issues with the cuff.
I hope you are feeling better.
Mark
