ELI5: Why is a carbonated drink so excruciatingly painful to drink for more than 3 seconds? (Why does carbonation hurt) 

Is it because the tissues in the throat are super sensitive, and the popping of the bubbles diddles around with it to the same effect of taking a needle and poking your throat but many many many times, because of all the shit tons of bubbles popping?

It's most likely because carbonic acid is soaking into tissues. Carbonation is carbon dioxide dissolved into water which forms the carbonic acid, which then spontaneously breaks down into water and carbon dioxide again when the liquid is no longer under pressure. While drinking, the acid levels on the nice soft wet tissues start increasing, but when you stop drinking the carbonic acid either breaks down into CO2 and H2O or gets washed away by saliva and other bodily fluid.
