i had noticed a yellowish pus filled looking spot on the back of my throat last week. it never hurt at all, just felt like i had something stuck in the back of my throat. it had been there a few days. then it went away. now i notice tonight it is back and there is some white spots all the way in the back of my throat. i have not had a sore throat at all during any of this, but i have been feeling more tired than usual lately. not sure if im just sleep deprived or if its something else. im scared i have herpes in my throat. i havent had anything like this before and i havent even given oral in months. just started dating someone and all i have done is kissing.
