RICE principle As an emergency treatment for ankle sprains, the RICE principle has become a classic: Rest: stop walking and let the injured part rest to minimize further damage; Ice: let the temperature of the injured part decrease to reduce inflammation and muscle spasms, relieve pain and inhibit swelling. Each time 10-20 minutes, more than 3 times a day, pay attention to not directly on the affected area of the ice, can be wrapped in a wet towel ice, so as to avoid frostbite. Ice should only be applied within 48 hours of the injury. Compression: Wrap the injured ankle with an elastic bandage and apply appropriate pressure to reduce swelling. Be careful not to overpressurize, as this may increase swelling and ischemia in the limb farther away from the wrap. Elevation: Elevate the limb above the heart to increase venous and lymphatic return, reduce swelling and promote recovery.
