A muscle strain, also called a pulled muscle, occurs when a muscle is stretched too far, and microscopic tears occur within the muscle fibers. Common muscle strains include pulled hamstrings, groin strains, and calf strains. The usual symptoms of this type of injury include pain, spasm of the muscle, swelling, bruising, and limited mobility.

The second cause is the overuse or overextension of the muscle; is usually occurs from lifting items that are beyond your capacity, too quickly, or continuously for long periods of time.
