HI, my nine year old daughter has started complaining of pain in the inside area of her right knee. She says it aches when she runs or jogs, but is usually fine when walking. She has had growing pains in various spots in the last year or so, but not in her knee. It's only the one leg that has been troubling her for the last 2 weeks. She doesn't recall hitting knocking it around to have caused the pain.
