I Was Sitting Down And Then Suddenly Felt I Couldn't

I was sitting down and then suddenly felt I couldn't swollow. It's fine with liquids and solids but when I just casually swollow sometimes it takes me about 2 attempts. I'm not stressed I don't think, I have nothing to worry about. Was a little bit shaky like I hadn't had enough sugar but eating enough and drinking plenty I just came on when I was sitting down. I'm 16 with Good health.
