Sexually Transmitted Diseases

[mavric]

form around June 2007, my pubic area start itching me, when i take a closer look, it was some water bumps, i went to the doctor, but at that time they had dried up in 2 weeks, so they gave me a general treatment. I got some pills call: trich acid, donocyclone (not sure thats the right spelling) and a injection,(supposely for gonorrhea). Anyways, about 2 month after, the same bumps came back. I took an HIV TEST (2 times), syphilis, and herps tested, all came back negative, and i still have the problem even now! some other concerns is that: sometimes i see some clear discharge/semen come form my penis (something like pre-ejuculation), i have a shape pain in my left testicle at times, left lower abominal pain at times and my pubic area badly itches before & after the water bumps comes up. Anyone that can give me a feed back on this problem or help me to diagnose this, would be greatly appreciated because this is stressing me now!
n.b they usually comes up burse in 2-5 days time and dryed up in about 2-3 weeks and comes back up about a month to two months time. (always like two water bumps)
