The other day, I was chewing gum and a small piece went down my throat. A day later, my throat began to be sore. When I try to cough the piece up, i end up gagging like I'm gonna throw up, but nothing comes up. But when I swallow, I feel it and it's also even hard for me swallow. Anything I can do, eat, or drink to get the small piece of gum out of my throat?
