Causes

A sprain occurs when your ankle is forced to move out of its normal position, which can cause one or more of the ankle's ligaments to stretch, partially tear or tear completely.

Causes of a sprained ankle might include:

• A fall that causes your ankle to twist
• Landing awkwardly on your foot after jumping or pivoting
• Walking or exercising on an uneven surface
• Another person stepping or landing on your foot during a sports activity
