As soon as it doesn’t hurt too much to put pressure on the ball of your foot, start stretching your ankle using the towel stretch. When this stretch is easy, try the other exercises.
You may do the following exercises when you can stand on your injured ankle without pain.
If you have access to a wobble board, do the following exercises:
Stand on a wobble board with your feet shoulder-width apart.
When you have mastered the wobble exercises standing on both legs, try repeating them while standing on just your injured leg. After you are able to do these exercises on one leg, try to do them with your eyes closed. Make sure you have something nearby to support you in case you lose your balance.
