Every Time I Swallow It Feels Like I Have A

Every time I swallow it feels like I have a small, I always think it is something like having a piece of parsley stuck in there, although it feels like that all the time. I have tried to "throw up" to get rid of whatever might be in the way, however, I breath normally and have no problem eating. It is just very annoying and, sometimes, disconcerting. I did have a doctor look into it at Kaiser a few years ago and he relplied that it was a "tear". I am not sure where, but after looking at drawings of the throat, I think it might be a tear in the epiglotis? What do you think? M
