Answer 2

Answer:

• A muscle strain, or pulled muscle, occurs when your muscle is overstretched or torn. This usually occurs as a result of fatigue, overuse, or improper use of a muscle. Strains can happen in any muscle, but they're most common in your lower back, neck, shoulder, and hamstring, which is the muscle behind your thigh.
