RICE Protocol
Rest: Stay off the injured (foot/ankle). Walking may cause further injury.
Ice: Apply an ice pack to the injured area, placing a thin towel between the ice and the skin. Use ice for 20 minutes and then wait at least 40 minutes before icing again.
Compression: An elastic wrap should be used to control swelling.
Elevation: The (foot/ankle) should be raised slightly above the level of your heart to reduce swelling.
