RICE: a mnemonic acronym for treating sports injuries.

Rest - Stop putting weight or stress on the injured part.

Ice - Apply ice to cool the area and prevent swelling. 45 minutes on, 15 minutes off.

Compression - Swelling is your body's way of immobilizing the part to prevent further injury. By compression with stretch bandages you can immobilize the area while reducing swelling and thereby speeding recovery.

Elevation - By elevating the injured area above your heart you decrease blood flow and further reduce swelling.
