Hello, I was exposed to HIV risk by being stung with a needle in my hand by two homeless in the street 3 days ago, I made anti tetanus shot and hepitatis vaccine , I feel tired and feel like having fever although when i ask my wife to check my tempratrure she says I am cold and also started to have mouth ulcer one on the side of my tongue and the other outside on the lip, my question is, can this be a symptoms of HIV? Am really terrified about this please answer me
