What happened to my ankle?

When I'm sitting down its kind of throbbing, and it hurts when I flex it, or when I push off of it while walking/running... It hurts on the outside of my ankle and I don't know what I did to it. What's wrong?
If it's nothing serious do you think I'll be okay the play in my soccer tournament this weekend? I'm playing 3-4 games and reffing 7.
PS. It's on my right foot and about a week and a half ago I had a knee injury on my right knee. Just thought I'd throw that in there.
Thanks

It could be anything from a sprang to a torn ligament or tendons. Really what you need to do is visit with an orthopedic doctor and have them look at it. Don't waste your time with just a regular doctor, Orthopedic doctors deal with this everyday and they will know what to do. Make sure you contact you physician and request a referral to an orthopedic doctor, this will keep your insurance company in the loop on paying for the expense.

It's possible you either pulled a muscle, sprained your ankle, or there is a nerve you damaged when you injured your knee. To be sure, it would be best to consult a doctor of a family friend who has experience in the matter.
