I have had some sort of discomfort at the tip of my penis for about 4 days..I had very little discharge (one day), but nothing on my penis, no pain in glands, no fever or anything else. The first couple of days stung to urinate, but now it tickles or nothing at all. I know that something isnt right for this to be ongoing for this long. I had tests, and current results show no immediate bacteria. Still waiting for other results, and havent had a blood test yet. Thoughts?
