A sprained ankle is an injury that occurs when you roll, twist or turn your ankle in an awkward way. This can stretch or tear the tough bands of tissue (ligaments) that help hold your ankle bones together.
Ligaments help stabilize joints, preventing excessive movement. 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.
Signs and symptoms of a sprained ankle vary depending on the severity of the injury.
Pain, especially when you bear weight on the affected foot
Tenderness when you touch the ankle
Restricted range of motion
Instability in the ankle
Popping sensation or sound at the time of injury
