KT,
Hang in there !! I tried Entyvio with no success. My Doc has put me on Rinvoq. Suggest it to your doc. I have had chronic pouchitis right off the rip. Thankfully, no ulcers(yet anyway.) However, my pouch is enlongated and there is massive bacteria buildup. Lots of swelling, pain. I also take 250mg x2 per day of Cipro. Every three weeks take a three day regimen of Flagyl. I hope this helps. I hope this helps anyone reading this ! Keep good thought !! Answers are out there !
