BL56 · 足太阳膀胱经

Chengjin chéng jīn · 承筋

Location. On the back of the lower leg, on the line joining Weizhong (BL40) and Chengshan (BL57), 5 cun below BL40, in the centre of the belly of the gastrocnemius muscle.

Named for the muscle belly it sits in; classical texts group it with the calf and with cramping of the leg.

定位。小腿后面,委中与承山连线上,委中下 5 寸,腓肠肌肌腹中央。

因位于腓肠肌肌腹之中而得名,传统文献将其与小腿肚及腿部拘急归为一组。

Classical record · not a treatment recommendation. Needling technique is a licensed practitioner's skill and is out of scope here.
Deep needling can reach the tibial nerve. Cramping that follows needling should end the session rather than be worked through. Practitioner skill.
