Hey Doc, well I m so concern I can t sleep. About 3 days ago I noticed my urine had an strong unpleasant smell. I tried drinking more water and eating things that dont affect the smell but today my lower back and my abdomine began to ache. While it doesn t hurt to go and i don t go to often, I am a bit itchy. But what worries me is that I also noticed tiny black spots on my urethral opening and a bit of swelling. My urethral opening doesn t itch, hurt or burn and I don t have chills or a fever but it is swollen. I will go to the doctor tomorrow afternoon but I m afraid it might be a UTI or worse an STD, please advice...should I be worried? Thanks.
