Ankle sprains may be caused by:

  • Falling
  • Sudden twisting of the ankle, such as:
    • Stepping on an uneven surface or in a hole
    • Taking an awkward step when running, jumping, or stepping up or down
    • Having your ankle roll over when playing sports or exercising—called inversion of the foot
