Ive had these same symtoms years ago and they lasted for a very long time. I went to countless doctors and my tests always came back negative. No UTI was ever found. They couldnt make heads or tails of what was happening to me. I was so convinced that I had some type of infection in my bladder, urethra, kidneys, everywhere, I thought it was eatting me alive. The strange thing is that once I accepted the fact that I didnt have anything, it went away, totally and completely. Sort of like what happened to the poster above me. So strange but true.
