Mix hot water with honey and drink it slowly. Grab a soothing menthol and you should be fine. If worse go see a doctor.
This is going to seem really weird, but it worked for me, hopefully you too if you try it. Mix about a spoonful of honey, three to five cloves of garlic (yucky) and about a quarter spoonful of cayenne pepper. Eat that a few times a day. Voila, gone. Since I dislike garlic, I also used the table salt directly to the back of the throat , let it rest a bit and spit "trick" (Ha!). The garlic is an anti-inflammatory/has healing "powers", the honey soothes the discomfort, and the cayenne helps with blood circulation. The salt, I can't remember what it does, but it worked. I hope this help, and if possible, get some rest.
