Conservative treatments for ankle sprains include basics like rest, ice, compression of the ankle, and elevation of the ankle. Once the leg is stabilized, elevation should take place. When elevating the leg with the sprained ankle, it is important to keep it above the level of your hips whenever possible. For the first two or three days after the injury, use ice on the sprain as often as possible. Also remember bracing and taping the ankle can make dramatic contributions to the recovery process.
If there is no improvement after several days or if swelling and pain are severe, consult a physician.
