First off, don't squeeze it. :-) Have her rest it right now. Motrin is good since it'll reduce pain and swelling. She could easily have sprained it or strained it without remembering having done so especially if she's not having any other joint or muscle pain. Hopefully the doctor will just have her rest it, continue to have her take Motrin, and have her continue to walk as normal (without a lot of physical exertion like climbing or running) until she feels better. He probably won't have her wrap it as wrapping sprains actually weakens the muscles and joints.
