Why can't i swallow anything?

So yesterday i had a throat ache and i thought i was coming down with strep throat, and today i woke up in my bed sweating. When i got up i almost fell over because of my dizyness, i felt that in my throat was hurting more then yesterday and that the top of my throat was clogged with flem. That happens to me a lot when I get a throat ache and i normally just swallow it or cough it up, but this time I couldn't... Anyone know why i couldn't, and what i can do to get it out?
