How long does it take for the swelling to go down in a sprained foot?

Sprained feet vary in the length of time that the swelling will last. First there are injured people that are prone to swelling and the severity of the injury needs to be considered. Best of all is RICE. Rest, Ice, Compression and Elevation are the best things to do for the injury. If the injury is less than 24 hours old, ice is important. After a few days heat can help with removing bruising but again, ice is important now.
