My ankle hurts and I don't know if it is sprained of not. Please help?

Last Thursday, in P.E, I was running at top speed and landed on the side of my foot really hard. It hurt really bad but I thought nothing of it at the time. However, it still hurts and slightly effected my sleep. It is slightly swollen and throbs a bit. Please help??
