Wisdom teeth swelling, awkward situation?

I got my 4 wisdom teeth removed 2 days ago and my face is still pretty swollen. Tomorrow I have to go to work, Im a camp counsoler so I see a lot of kids. They aren't going to understand that my face is fat because of surgury, they're just gonna think I'm messed up! Is there anything I can do to "disguise" my fat face so it doesn't look as bad?
