I was wondering if anyone else has frequent UTI's while on Crohn's medications. My doctors seem to be perplexed by my frequent UTI's, and I just keep taking antibiotics to treat them. I've had a urethra scope (very painful) but they say nothing is wrong. It's very worrisome for me. I drink tons of water and starting taking D-Mannose, a supplement that is supposed to support the urinary tract. And sometimes I test negative for the infections, but I still have the burning associated with a UTI. My GI just shrugged and said it was probably the Crohn's. I'm currently in and out of a flare. I was on Humira for a year, and it just stopped working. I'm now on Remicade and praying it will put me in remission. Does anyone else have this problem?
