Moment Queen Mary winces in pain and begins limping before being rushed indoors

Queen Mary has been rushed indoors after being struck by a painful ailment in the middle of an official appearance. The Australian-born royal was accompanied by her husband, King Frederik, 57, their daughter Princess Isabella, 18, and son Prince Vincent, 14, at an event in Gråsten, Denmark. While greeting her admirers, Mary, 53, who was carrying a bouquet of flowers given to her by one of her fans, suddenly winced and grabbed at her leg.
