Unfortunately my daughter (8) fell up the stairs at a shopping centre yesterday and landed on her knee. Apart from the initial shock and tears she said she was fine and we went on with our day including running in park etc. This morning her knee "very slightly " hurts but it is clicking when she bends it up. She can make it make a click sound constantly. Any idea what she may have done? Is it serious? She is due to be at dance camp all this week and I don't want her doing anything that will do permanent damage but at the same time she does not want to go see a doctor that says she can only rest for next week(s). Thanks very much.
