How to reduce swelling overnight?

I got into a fight like an hour ago and i got hit with a bottle right under my eye and it's cut open a bit and swollen. There is a bit of bruising but nothing too major. I covered it up with concealer and translucent powder but it's still swollen. How do i reduce the swelling overnight? I have school tomorrow and i don't want a lump under my eye. And also I don't know what happened but on the top of my foot it's all red and a little swollen as well, it hurts to walk on but nothing feels broken or sprained. What could this be?
