What to do about a multivitamin that was/is in my windpipe?

For the past couple days, my throat hurt well below my adam’s apple when I would move my throat into a position to make a deeper pitch. You know, how your adam’s apple drops lower when you go to use a deeper voice. Just an hour or so ago I remembered that 6 or 7 days ago I took a men’s multivitamin. I didn’t have anything to wash it down with. I placed it in the back of my throat, and it slipped down. I thought nothing of it, but I should have. I didn’t swallow it, It slipped down my wind pipe.

For the past hour I’ve been leaning upside down, tapping at my throat, exhaling violently, coughing, and trying to force it out of my wind pipe if it were still there.

Would it have dissolved? They’re pretty dense and large? If it is still in there, how should I get it out? If it isn’t still there, and it is just irritated, how can you assure me that it has disolved? But, I’m almost certain that its still in there. What should I do?
