Hello. My problem started out two or three days ago when I had extreme pain in my throat. There was a little white tonsil stone on my left tonsil, but I eventually got it out. Since then, my throat feels very swollen, and even swallowing my saliva is unbearable because of pain. I have been experiencing post nasal drip, but I have always had seasonal allergies. It has never been like this. My ears and teeth heart, and now there is a swollen lump on my neck behind my ear.
