A) A twist, pull, and/or tear of a muscle and/or tendon.
A strain is an injury to a muscle or a tendon, which is the tissue that connects muscles to bones. This type of injury occurs when a muscle or tendon is overstretched or torn. This can happen due to an acute injury, such as lifting something heavy improperly, or as a result of repetitive movements or overuse over time. Symptoms may include pain, muscle spasms, swelling, and limited ability to move the affected muscle.
Strains are categorized into different severity levels: - Grade I: Mild strain with only a few muscle fibers injured. - Grade II: Moderate strain with more extensive damage and more muscle fibers affected but the muscle/tendon is not completely ruptured. - Grade III: Severe strain that represents a complete rupture of the muscle or tendon.
It's important to note that strains are different from sprains. A sprain is an injury to a ligament (the tissue connecting two bones), which often occurs in joints such as the ankle or knee. The severity of a sprain or strain can vary greatly and is not defined by whether it is a sprain or strain.
