Hello, I Have A Very Sore Throat On My Right

Hello,

I have a very sore throat on my right side that randomly popped up today with only a cough or two (thought that could have been from anything). I see two red things on my right tonsil while my other looks fine. I also have a pain in my throat (tonsil) and my right ear when I swallow. I work at a daycare so I do not know what it is I could have picked up.

Thank you,
Evany
