You want the foot to be higher than your heart. Dont worry, your heart will pump blood to your foot. If you leave it below the level of your heart, blood will accumilate around the injured area leadding to swelling. Elevating it encourages blood to flow back to the heart via the venous system. Even days after the injury elevation is still a good idea.
