What is the difference between a sprained ankle and a sprain?
assistant
A sprained ankle is an injury to the ligaments in the ankle. It is usually caused by twisting or turning the ankle too quickly, which causes the ligaments to stretch beyond their normal range of motion. A sprain is an injury to the ligaments that results in swelling and pain. Sprains are often caused by sudden twists or turns to the ankle, but can also be caused by falls.
