I hope that this is not your case but I went through an experience like this where the antibiotics were not working and then my uti lead into a kidney infection and I was miserable. I also found out that I was allergic to Bactrim and another medicine that was given to me so that doubled my misery! anyway, I found out that I was getting these from my live-in boyfriend, who finally admitted that he had made a habit of having unprotected sex before we had gotten together! things are fine since I am no longer with him!
