I gave a guy oral sex one night, two days later I had a sore throat. A few days later still have the sore throat and a little discomfort when swallowing, it also feels like I have something stuck in my throat almost. When I looked in the mirror today I noticed white spots on my uvula which explains the feeling of something being in my throat and also one back by my tonsil. I don't think it's strep because when I get strep I have different symptoms. What could it be?
