Yep, chemo does some interesting things to our evacuation system. I was walking 5km a day but it got too scary as when I needed to go, I needed to go. My gut is still not right. When you go back to the doc's, it's a simple test to check for UTI and it's worth getting it ruled out (pre-BC I had slight symptoms of UTI for a day - smelly & irritated - the symptoms disappeared but I ended up in hospital 2 weeks later as the infection had actually travelled up the urinary tract) but more than likely, it's just good old chemo.
