Well she most likely broke her ankle or popped it out of place or something. I would try to get her to the nearest emergency room so things won't get worse than it already is, or if I'm not able to go I would most definitely call 911 so they can send the paramedic's.
She has probably twisted or sprains her ankle and the best way to treat it is to put ice, let it rest, and depending on the severity, you may need to take them to the hospital.
