肩井 - Jianjing (GB 21)

肩井 (Jiānjǐng / GB21), the "Shoulder Well," is a key point located at the midpoint between Dazhui (GV14) and the acromion on the shoulder. It is a specific point for releasing neck tension, treating shoulder pain, and promoting lactation. While effective for musculoskeletal disorders, acupuncture carries risk of pneumothorax and MUST be performed by a qualified practitioner.
