I have felt an increase in the need to go to the bathroom. There is no pain. The color of yellow seems to be a little brighter than normal. This has been going on for about 2 months. On Oct 29th and around Nov 20th, there was blood in my urine but it didn't happen any other time (last March I was doing the splitz when I normally don't do that and I had blood in my urine for about 3 days but my doctor was not concerned and tests didn't show any infection,,etc). I have also had soreness in my lower back also since Oct 29th.
