Where should I start? I am a male age 21. About 4 months ago I had vaginal sex with a female(used a condom but at some point it slipped off). A month after I experienced some symptoms typical of an STD (only at night/evening) such as burning in the urethra and in the head of the penis, frequent urination (no discharge to my knowledge) and pain in my side while sitting. I went to a doctor (4weeks after) had std test done for HIV Syphilis, gonorrhea, chlamydia and Herpes, all of which came back negative. The symptoms subsided for a week or so then I got a pain in my right side, at this point i went to the doctor had a prostate exam and he told me I had a swollen prostate and my symptoms were in fact that of prostatitis which can occur in a male of my age. He placed me on Bactrim, for a month, however i had to stop taking them after around 1 n 1/2week due to a reaction to sulfa where my entire body would feel itchy and i developed rashes, night sweats and a swollen lymph nodes in my neck which he states were caused by an allergic reaction to sulfa in the Bactrim. After i had stop taking the bactrim symptoms went away immediately and i felt okay until a week or 2 after. I had the worst experience of my life. The burning in my urethra and the tip of my penis came back with a vengeance and it was difficult to sleep because i could feel the swollen prostate.I also notice that my urine and semen had a fishy odor to it. The head of my penis also burnt after ejaculation or urination. I decided to go to another Doc after 3months where he gave me a complete test. He check my urine and blood for bacteria and over production of white blood cells etc. He check for Herpes and HIV. All test came back negative. He put me on Cipro for 1 week. After the Cipro was finished, the burning in the urethra had stop but a slight pain in my prostate was still there at nights for a while. About a week ago (3weeks after i finished the cipro) i realize that the pain in my prostate felt as if it was gone but now i feel the burning in my urethra and penis returning again as it did before. I am convince that I must have contracted some sort of virus or bacterial infection or STD from my sexual encounter. None of these symptoms ever happened before my sexual encounter. I asked the female if she could have some test done which she agreed to, she stated that all her std test were negative (but who knows if she is telling the truth).
1) what STD could have caused my prostatitis? is it possible for it to go unnoticed even with testing?
2) What other factors given my situation may have caused theses symptoms
2) I notice each time i take antibiotics my symptoms seem to go away for a while, when i stop they return in a few weeks....would a longer treatment of antibiotics help?
3) is it possible that my prostatitis maybe due to Herpes even though i have no discharge or scores and testing was negative?
Any help is appreciated
