Thank you for your reply. I just came back from my urogydnocologists office where I learned how to self-cath in an effort to stop UTI's and bladder pain. Not fun! It's agreed that BPS/IC is a logical possibility. I had a cystoscopy done last month as part of a sigmoid colon resection surgery. The urologist said there was nothing unusual with the lining, but I did have a UTI. I also had 3 different pelvic CT done in 8 weeks for the colon perforation, but nothing was found on the bladder. I'm hoping for better answers with my new urogynocologist. I see her again next Friday.
