The problem started after having unprotected sex with my girlfriend. Initially it was a strange tingle/itch type feeling at the tip of my penis with resulted in a weakened pee stream. I went to the doctors and got tested for a UTI, which came back negative. They recommend getting an STI test due to the vague nature of my problem. However the STI test also came back negative. Over the past couple of months the tingling sensation has died down significantly since the first couple of weeks, but it s more or less always been and still is there. However I have noticed a couple of other symptoms in the last month or so; not painful but more uncomfortable. Firstly I have had a bit of a dull ache in my testicles, again it s not that painful but I can feel it there. Also, I ve noticed that when I drink alcohol, even small amounts, I will always end up with a very irritable stomach the next day. If and usually when I m sick with this, traces of blood come up with it (although I m unsure if this is coming from my gums as they bleed sometimes). Regardless, it s strange since I never got an upset stomach after drinking until my problems started. I also went through a phase where I lost my appetite a bit and was quite fatigued. I also feel some tension in my pelvic floor area from time to time as well. Again, these haven t stopped me going about my normal life and the symptoms aren t causing me pain, more discomfort. Can I get an opinion on if it could be anything and what it may be? Update: I was prescribed anti biotics for a bladder infection. Symptoms cleared up for a short period however they have returned since. Generic Blood/Urine tests came back normal. Thanks.
