Injury!

I've been trying to work this roundoff-backhandspring-backtuck with good technique and height, but the top of my ankle screams in pain when I punch the floor, rebound, and land. It's noticeably swollen tonight. Been wearing a neoprene ankle brace, but it doesn't seem to help too much. Any coaches out there know anything about ankle injuries?

Can't evaluate an injury very well over the internet. Get it looked at if the pain continues, is acute or extremely swollen.

Swelling and pain >> go to a doctor! This should be common sense.
