About a month ago, I had definite symptoms of a UTI. I took septra. I did not have any health insurance so I didn't go to the doctor but after a week, the pain went away when I used the bathroom. And for the most part, I feel better. But I still have some irritation in my vagina. It burns and itches in there. Should I be worried? I did sleep with someone right before that and I am worried taht he may have given me something now.
