I've been having pain during and just after urination for a few months now. It's a harsh burning feeling and it's very frustrating and uncomfortable.

I've given 2 urine samples in, both which didn't show infections but the second did show some "puss ulcers" or something? They have asked me to produce yet a third sample.

I am getting very worried over this and not sure what to expect.

I'm only 21 (male) and I don't know if this could be relating to any prostate problems or anything? I really have no clue, but my Doctors aren't working on this very fast and it's really stressing me out!

Any help please :-(
