Get to a doctor. Do it NOW! This could do several things, none of them good, such as:

1. cause scarring and eventual closure of the throat
2. work itself loose and find its way to your lungs, causing a pneumonia which might very well kill you
3. cause infection and septicemia -- which can kill you and hospitalize you
4. work its way into the tissues and migrate to your vocal cords

as well as other things.

The doctor will put you under an anesthetic, and if not ask for one.

How many other people this happens to is irrelevant. This time it's happened to you.

But, then again, it's your life, your throat, and if you want to end up breathing through a stoma and burping your words, it's not my concern.
