A sprained ankle occurs when the ligaments are forced beyond their normal range of motion. Most sprained ankles involve injuries to the ligaments on the outer side of the ankle. Treatment for a sprained ankle depends on the severity of the injury.
Sprained ankle. Diagnosis. During a physical, your doctor will examine your ankle, foot and lower leg. The doctor will touch the skin around the injury to check for points of tenderness and move your foot to check the range of motion and to understand what positions cause discomfort or pain.
In the case of a severe sprain, a cast or walking boot may be necessary to immobilize the ankle while it heals. Once the swelling and pain is lessened enough to resume movement, your doctor will ask you to begin a series of exercises to restore your ankle’s range of motion, strength, flexibility and stability.
