the twin 'bellies' of the gastrocnemius are prominent in the upper half of the calf, e.g. when standing on tip-toe; this and the flatter soleus in front of it (known together as the triceps surae ) form the main bulk of the calf muscles; their tendons join to attach to the calcaneum via the Achilles tendon. Accessory to the gastrocnemius is the plantaris . Deeper muscles include the flexors of the toes, with long tendons passing into the foot. See Figure 1.

Patient discussion about calf

Q. I have just developed a pain in my calf - feels like it clicks when I walk, and is a sharp pain I first noticed this problem this morning. As I stepped out of my car, I felt a sharp pain in my left calf, and it has gone worse as the day has gone on. No pain until I walk.

A. as i think of it- fatman's answer seems more logical. but usually people can tell the difference between strained muscle and other stuff. if it was just a pulled muscle he would have thought of it and naturally massage the area. no?
