Hi My Throat All Of A Sudden Became So Dry

Hi my throat all of a sudden became so dry and when I checked my throat I noticed a just a red dot on my uvula as if it was bleeding, should I be worried? My wisdom teeth is also growing and it caused half of my face to swell up and pain in my left ear. I can't take the pain. My body feels weak as if I am about to pass out or die because I can't eat as I please due to the teeth. I've been relying mostly on liquids
