Not feeling well for some reason?

Yesterday I was drinking a vault red blitz soda. my throat started to swell up and get itchy. i just went along with it figuring it will go away. but instead of going away i started getting a headache, there was alot of mucus in my throat but it still felt dry and itchy. and to add on to that my ears started ringing from the headache im guessing. I woke up this morning , there was mucus all over the inside of my mouth. and i feel warm and cold at different times.
