Yesterday I went to pee and had a very hard time because it was so painful with a burning sensation, I later tried to pee again and there was also a burning sensation. I thought it may be a bladder infection so drank a lot of of cranberry juice and this morning all day when I went pee it did not hurt at all, but now I noticed a red bump by the pee hole. I have only had sex with one partner and they are std free, this first time eexperiencing this pain was 24hrs ago after sex, the pain is gone but now there s a red bump.
