So this morning I (regretting this decision) ate a box of Sour Patch Kids. Ever since, I have a 'burning sensation' on the back of my tongue whenever I try to eat something. I don't have any allergies that I know of, but maybe I'm now allergic to artificial sourness? 

Has anyone else had an experience like this? Also, any ideas on how to make it so I can eat without my tongue hurting like hell?

I've tried brushing my tongue, with and without toothpaste, gurgling water on it, eating ice cream (which helped it numb a bit but its fully back now). It's been seven and a half hours since I've eaten the Sour Patch Kids. 

It's driving me insane.

Help.
