Hi. I had a piece of plastic fly into my mouth earlier this evening and was stuck where my throat meets my nose. I managed to dislodge it, but not get it out. I think I may have swallowed it. I'm not having any trouble breathing, but I'm feeling a small pang barely left of my sternum here and there, though I feel it's from worry. If I did swallow it, is there any danger? Should I rush to a hospital? If it did go down my windpipe, other than choking (which I'm not) is there any other way to tell?
