I had the same thing in Feb. I went on Cipro and flagyl and that did the trick. I was on it a while and it kept my inflammation at bay. I just recently went off of it due to pregnancy and it hurts again. The doc prescribed Canasa suppositories but I can't get them in! They pop out! How's that for a visual?
I would ask the Gi about some other meds or staying on the anti-biotics.
