Two hours after the ankle sprain, the ankle needs to be strictly immobilized, regardless of the presence of a fracture, by wrapping and immobilizing it with an elastic bandage or a slightly rigid object. The affected limb should be elevated and treated with a cold compress to reduce the exudation of intertissue fluid and reduce the degree of pain and swelling. If the ankle sprain is severe, an x-ray should be performed to determine if there is a fracture and to assess for ligament damage. If necessary, an MRI can be done to determine the diagnosis. Analgesic medications should be used to reduce pain after ankle sprains.
