I have been having uncomfortable pain in my urinary track. I have had UTI s in the past and thought about a month ago I had another one. I went to the doctors and the urine sample came back with some bacteria, but negative for an infection. I have completely stopped having sex, drinking anything with caffine and going to the bathroom as soon as I feel the urge to try and eliminate this for about a month. It hurts at the end of my urination , when I sit and move my pelvic area and sometimes when I am walking. The odd thing is, is it doesnt happen all the time. What should I do?
