Shoulder and back pain, inability to raise the arm, stiff neck, mastitis, strong nape, hemiplegia due to stroke, dystocia, postpartum blood syncope, tuberculous lymphadenitis, hypertension, and functional uterine bleeding, etc.

On the shoulder, directly in front of the nipple, at the midpoint of the line connecting Great Vertebra (GV-14) and the tip of the acromion. (This acupoint is bilateral, one on each side.)

Step 1: Sit down, lower your head;
Step 2: Determine the posterior median line: that is, a vertical line made in the center of the back;
Step 3: On the posterior median line, there is a noticeable protrusion on the vertebrae at the junction of the neck and upper back;
Step 4: This protrusion is the spinous process of the 7th cervical vertebra, which can move with the neck's left and right rotation, and there is a depression below this spinous process, which is the Great Vertebra (GV-14) acupoint;
Step 5: The midpoint of the line connecting Great Vertebra (GV-14) and the highest point of the shoulder, when aligned with the center of the nipple, is the location of this acupoint.
