I'm very worried that I might have caught something , and don't know what these symptoms are a few weeks after an drunken encounter . two weeks after encounter around late night ,burning sensation on my testicles ,and warm feeling on penis plus sharp tingle on and around shaft. Sometimes itchy shaft . itchy pubic groin area ,burning thighs ,tingling anus on and off.Itchy calves I been scratching at the most random times .the main thing that scares me is the tingling in penis and anus. Im 100 percent I didn't have clamidya, gonnorea,HIV ,aides in the first place since i did not have sex with anyone prior this encounter and decided to get tested regardless and everything came up negative . I'm worried about syphillis ,HPV,and herpes as the main suspects of my symtons though I think i tested to early for siphylis and hsv2 i tested two weeks for siph prior encounter and hsv2 a month after . and got negative for both . I've had no lesions nor bumps yet for the passed two months . I just can't find the suspect of these symptoms and its stressing me out thinking I have a disease .any advice ? Should I get a retest for hsv2?,and maybe HPV.
