Train driver Andy, who's 48, is rushed to A&E after falling 12 feet from a tree while cutting branches. Andy landed on his feet and has badly fractured both ankles. He doesn't have any sensation in his feet and doctors are concerned that the impact may have caused life-changing damage to critical nerves and blood vessels in his feet and legs. Medics decide to cut the skin on his calves to relieve dangerous swelling. Andy will need major surgery.
