I do not have a history of pouchitis or inflammation. My output has always been frequent and not very bulked. I had a capsule endoscopy a few years ago and all was fine. I do not play contact sports but I am an endurance runner and regularly train for marathons and half-marathons. I get a physical every year and with the exception of a j-pouch I am in great shape.
My colorectal surgeon who fixed the perforation consulted with other surgeons in her practice,they had not seen this before in a pouch. My GI said that I could have just moved the wrong way. Needless to say, the uncertainty of why/how this happened has caused a significant amount of anxiety. In fact, I was in Tampa on business this week and went to the emergency room because I was feeling similar symptoms (I actually had to get off a plane after the door was closed). The CT scan showed a full pouch that could have been causing discomfort and pain, luckily no perforation or leakage.
