Yesterday I had something stuck on the side of my throat. Last night I looked and there was a whitish blob back there--it was likely popcorn. So I pushed at it and got it off that side. Now I think it's stuck at the back of my throat, because I can still feel something there, and my throat aches. I've tried drinking both hot and cold drinks to get it out, I've eaten, and I've tried coughing. Short of inducing vomiting, is there anything I can do to get it out?
