For the past 4 or 5 days now i've gotten this feeling on and off that I have a lump deep in my throat. It kind of feels like mucus. I did drink a whole lot of alcohol last friday, and noticed it the next day. The feeling comes and goes. I have been drinking a lot of coffee with creamer, but I have never had a problem like that before. Could this be the sign of a cold? I've had the feeling pretty much all day. Or is it something far worse....I'm really scared. Any input would be appreciated.
