two years ago i had unprotected sex with 3 guys, (gay), this past year i am getting every symtom in the book, when i get sick its horrible, lymph nodes swell at times, rashes, and even i looked up rashes and something about a dry scalp came up and i have flakes on my head and a very dry scalp. the catch is these guys i know and are hiv- so what is causing these major symtoms of this virus. i dont get it.
