Hey, I Am Experiencing Extreme Dryness In My Throat Followed

Hey, I am experiencing extreme dryness in my throat followed by a targeted pain on one side of my neck. I also see some swelling on one of my tonsils, however there is no redness, or white spots. In addition to all of this I have a mild headache that tends to come and go. In the mornings it hurts to swallow but after eating and drinking, the soreness decreases. At night i feel aches and a bit feverish. This all started about a day or two days ago. What could it possibly be?
