Point Region: Lower leg
Location & How to Find
Anatomical Location: On the outer side of the lower leg, just in front of the fibula, 5 cun above the outer ankle bone.
Distances are in cun, a unit that scales with each person's body. As a guide, the width of your thumb at its joint is 1 cun, and your four fingers held together, measured across the middle joints, are 3 cun.
How to Locate:
- Find the most prominent point of your outer ankle bone
- Measure four finger-widths plus two thumb-widths up the leg
- The point is just in front of the outer leg bone (fibula)
How to Apply Pressure
Measure five cun up from the most prominent part of your outer ankle bone, just in front of the fibula. Apply gentle, steady pressure there with a fingertip. Keep it comfortable: firm but never painful, and never deep or unrelenting. Stop if it hurts. Avoid this point if you have severe eye diseases requiring medical treatment, acute leg injuries, retinal disorders.
