Arggh Injured

Its a bummer being but the best thing you can do is take action. Your body doesn't stop working just parts of it aren't. If you hurt you knee train your core or upper body or worst worst comes to worst just focus on your mind. Even the very best athletes get injured or sick, it's just something you need to deal with. Obviously RICE in the first 24 hours and plenty of stretching and heat after that. Good Luck.
