Food stuck in throat?

Well I'm 15 and I as playing on xbox when I suddenly laughed while eating a KitKat >.< and I chocked on it so I went to get a drink and this was around 3pm, it's now 4:47am, And I had no sleep becuase of it, Do yo think it is stuck in there? What should I do to get it out? Phone GP? or is it just that apparntly weird thing with the muscles in your throat because the back of my mouth is really red and when I swallow I feel something likefood stuck there? Help please? No there arnt White dots at the back either...cane it feels just bellow my Adams apple.
