Thanks again for answers.

I will not die because of this, I am sure. Its not a big 5 centimeters chickenbone, but only a small piece of a bone. Maybe its less than 0,5 cm in diameter or length. So these "You are close to death"-statements some of you have had are exaggerations.

The worst that can happen to me, is that the piece gets loose and enters one of the lounges. Or an infection.

I have had it for 4 days now. So maybe its time to go to a doctor, because it doesnt go out, whatever I eat.
