What is a calf strain?
A person with a calf strain has stretching or tearing of the calf muscle, called the gastrocnemius. A calf strain is usually caused by an injury. Most calf strains are partial tears of the gastrocnemius. Severe calf injuries may cause a complete tear through the gastrocnemius, called a muscle rupture. Injuries to the calf may also result in Achilles tendon rupture.

How does the doctor treat a calf strain?
Treatment for a calf strain includes rest, elevation, cold compresses, and crutches. Nonsteroidal anti-inflammatory medications may be prescribed for pain. Later options include massage therapy and physical therapy.
