Will a sprained ankle require you to wear a leg boot or a cast?

Ankle Sprain: It may heal on its own with rest, ice, compression and elevation and a gradual return to your normal activities. However, a period of time in a boot or use of crutches may be necessary depending on the severity. A physical exam by an orthopedic physician will better be able to determine your appropriate course of treatment. Hope this helps and good luck!

Depends on severity.: Depending on the severity of the injury you may need an ace bandage, strapping of the ankle, an ankle support brace, a rigid walking boot, or a short leg cast. Have it evaluated by your podiatrist and see what is best for you.
