Minor injuries like sprains may be treated at home if broken bones are not suspected. The acronym RICE is helpful in remembering how to treat minor injuries: "R" stands for rest, "I" is for ice, "C" is for compression, and "E" is for elevation. Pain and swelling should decrease within 48 hours, and gentle movement may be beneficial, but pressure should not be put on a sprained joint until pain is completely gone (one to several weeks).
