I was chewing gum, I coughed, and I felt the gum go down my throat. I became terrified, thinking that it went down my windpipe. I started coughing, then I started throwing up. I feel like I can still feel something in my throat, but it could just be my extreme paranoia. If it helps, the vomit tasted like the gum I was chewing. What should I do? Please help.
