There's a problem with my throat?

I have puss in the back of my throat it only started about a day or two ago. There is no pain, i can still eat, it's a little irritated, no itching, I just feel like there is something stuck in the back of my throat. Its like little spots of puss.(i'm not trying to be nasty) My sister says it could be herpes, but the thing is i think that i would have caught it elsewhere before i caught it on my throat. Maybe it's just strep throat, even though i've never had it before. Does anyone know what could be wrong?
