Finish the treatment with ice to flush the debris away. When an injury occurs remember to ice first. In addition to the ice, elevate the injured area above the level of the heart. Gravity will help to reduce the swelling. Use an ace bandage to compress the injured area and hold the bag of ice loosely in place.
RICE stands for rest, ice, compression and elevation.
If there is any doubt about the severity of the injury consult you doctor first.
