Location
On the shoulder directly above the nipple at the midpoint of the line connecting GV14 and acromion the at the highest point of the shoulder.
Cautions
Avoid deep needling – risk of pneumothorax. Traditionally forbidden in pregnancy – these are the points used to bring on labour at term. Controlled data show no excess of preterm birth or stillbirth (Carr 2015), but in pregnancy needle only on a clear obstetric indication.
Indications
