I am a 26 year old male, and One day I am not peeing much at all, the next I am peeing to much and even when I do pee when I am finish it still feels like I have to even when I don't ( which is very uncomfortable) and my urethra keeps itching. and yesterday I was having flank pain on my left side. my urine isn't any darker than usual, I did notice it looks like little pieces of white debris floating in my urine, but I read thats normal. whats going on ? the doctors has found a small amount of blood in my urine, but they didnt find any infection or bacteria.
