I love working the gastrocnemius trigger points. No other muscle seems to have as much “bang-for the-buck” for both the therapist and the client (but the soleus muscle is a close second). Call me crazy, but sometimes I think every case of myofascial pain (from headaches to foot pain) has it’s origin in the calf muscles. Of course I have found no medical science to support that claim, but when it comes to the peculiarities of the nervous system, who really knows?
