The Gastrocnemius is part of the composite muscle known as the Triceps Surae, which forms the prominent contour of the calf. The Triceps surae comprises the Gastrocnemius, Soleus, and Plantaris.

The popliteal fossa at the back of the knee is formed inferiorly by the bellies of the gastrocnemius and Plantaris, laterally by the tendon of the Biceps Femoris, and medially by the tendons of the Semimembranosus and Semitendinosus. The gastrocnemius has four pain maps, one for each of the proximal and distal medial and lateral portions.

Here below we have a map of the medial head belly; one can see the referred pattern into the medial border of the foot as well as an extensive medial calf to mid hamstring pain pattern


Calf pain and night cramps are commonly associated with gastrocnemius trigger points. Trigger points in the gastrocnemius are often related to footwear so it’s always a good idea to check or ask about the types of shoes people wear. Another common generator of trigger points is start stop driving for hours on end.

How do you treat trigger these trigger points? We’d be delighted if you want to share your own best practice.
