How can I unclog my ear help I can't hear?

So to make a Long story short I have been dealing with an upper respiratory infection and it seems to have moved up into my head. I am on antibiotics. The problem is it feels like I have stuffed cotton balls down inside of my ear, I can barely hear out of it. It also hurts down into my jaw somewhat. I poured peroxide in my ear and it helped for a little while and got bad again, what the heck is in my ear and how do I fix this? It's so annoying. People are having to yell at me because I can barely hear out of my ear and the other ear feels sensitive, it's like it's trying to make up for the other ear.
