Is English the first language of the person who said, "recovered"? Is it a translation? Could there be a cultural difference in the way it's used in this context, such as " Out of the recovery room, awake and lucid after anesthesia," etc.?
As far as numbness in the leg, I've experirnced it whenever I've had a sciatica attack, hardly the end of the world (even if it felt lie it at te time), and I'm guessing this isn't the first time an athlete with back problems has experienced it.
