Sprained ankle?

"rolling" your ankle, usually indicates that you have some version of a Sprain (ligamentous) or Strain (muscle/tendon). My guess if you are walking with no limp and can jump up and down on it without any shooting pain is that with an ankle brace for support you should be able to play. The hard part will be cutting side to side and obviously coming down on it from a lay up. Long story short--ICE ICE ICE, 20 min. on, 20 min off. If you have swelling around the outside ankle joint (fibula and lateral ligs.) make sure you are keeping it elevated to keep the swelling out of your foot. If you do have pain to walk, don't play - it isn't worth it. Aside from icing it down for a few days to longer than a week you should look up Ankle Stretching (heel chord) exercises, And general strengthening exercises (heel raises, single leg balancing). Good luck to you--the best athletes take care of their bodies even if it means missing the big game!
