Ankle Sprain
Signs and Symptoms

If there is a severe ankle roll, the forces cause the ligaments to stretch beyond their normal length. If the force is too strong, the ligaments can tear. You may lose your balance when your foot is placed unevenly on the ground. You may fall and be unable to stand on that foot. If enough excessive force is applied to the ankle, you may even hear a "pop" sound. Pain and swelling will result after the injury.
