Sex with wife (of 3 yrs) early July....stopped because she was due with first child first week of August....late August felt a sense of stinging at end of penis, then burning when urination. NP did urine test (found bacteria) and 7 days of macrobid....bacteria was gone but week later, still symptoms and after another urine test, it came back clean....but still "burning sensation" within penis. So, NP gave me 2 weeks of bactrim....which did nothing. Went to urologist who did tests on urine, PSA and prostate check...all came back fine. He put me on a month of cipro 500mg. He didn't specify what he thought it was besides "this is just a part of being a guy".No discharge and feel a pinch/sting when I urinate through day. Again, urine continues to come back clean....and seems to feel not as bad in the morning, then worse throughout day. Lastly, when my bladder becomes full, the feeling worsens...With all of that, what on earth could be issue? It's been close to 2 months now and I'm feeling hopeless.
