Omg so why does the right side of my throat and the roof of my mouth hurts when i swallow?

It's not itchy when I have a cold or anything. Just excruciating pain.

And also the right side of my teeth hurts at night. I tend to bite down on my teeth at night but i've never had any pain when I wake up. (I don't grind my teeth just bite) but lately since new years it's been hurting since day after new years.

UGH!
