How is BL-42 related to BL-13?

BL-42, also known as "Yunmen," is indeed situated laterally to BL-13, which corresponds to "Feishu." In anatomical terms, BL-13 is located on the back, at the level of the 3rd thoracic vertebra, approximately 1.5 inches lateral to the spinous process. BL-42 is found along the same vertical line as BL-13 but is positioned more laterally, specifically about 3 cun from the midline in the thoracic region.

Recognizing the spatial relationship between acupuncture points is crucial for practitioners, as accurate point location is essential for effective treatment. Understanding that BL-42 is lateral to BL-13 helps clinicians to navigate the back and thoracic areas more accurately, leading to better point selection for promoting health and alleviating ailments.
