why do muscle tears occur
A sprain is a stretch or tear in a ligament. Ligaments are bands of fibrous tissue that connect bones to bones at joints. A strain is also a stretch or tear, but it happens in a muscle or a tendon. Tendons link muscles to the bones. How Do Sprains Happen? Sprains usually happen when a person falls, twists, or is hit in a way that forces the body out of its normal position. The most common type of sprain is a sprained ankle. About 25,000 people sprain an ankle every day.
