So most times when i urinate, it stings and burns and cloudy, sometimes its bareable, and other times its horrible where im in crucial pain. So i went to my GP and got a UTI test and the results came back clear. I was also tested for a STI and it came back clear so ive no idea whats going on. In the meantime the doctor give me anti biotics and ive took a weeks course, which was 2 tablets a day (250g) for 7 days. Ive no idea whats wrong and the doctors dont seem to know either so they asked for another urine sample and i sent it away today. I'll get the results next week but no doubt it will come back clear of infection. Im a male, 19 nearly 20. Any ideas what it could be? Thanks.
