1Where is Dannang?
On the upper outer leg, 2 B-cun straight below GB34.
GB34 is the hollow in front of and below the head of the fibula.
There is one on each leg.
Fibula · Extensor digitorum longus · Fibularis longus muscle
2How do I find it on my body?
- Find the head of the fibula below the outer knee and the hollow in front of and below it (GB34).
- Taking knee crease to outer ankle tip as 16 B-cun, go 2 B-cun straight down from GB34, about three finger-widths.
- Feel around there and pick the most tender spot.
A cun is a body-scaled unit of length. The precise way is to divide a bone length into equal parts (proportional bone cun); finger widths are a quick estimate.
- extensor digitorum longus
- A muscle running from the outer front of the shin across the top of the foot to the 2nd–5th toes. Lift your toes and four tendons fan out on the top of the foot.
- common fibular nerve
- A branch of the sciatic nerve that passes the outer back of the knee and wraps around just below the head of the fibula. It lies right under the skin over bone there, so pressure easily makes the outer leg tingle.
3Before you press
- The common fibular nerve runs shallow behind and below the head of the fibula — do not press hard or for long, and stop if tingling runs to the top of the foot.
- If you have severe pain under the right ribs with fever or yellowing of the eyes, do not wait on acupressure; seek medical care at once.
- Avoid broken or swollen skin and press only to a comfortable level.
- Acupressure is not a substitute for medical care.
4How has it been used traditionally?
- The name is the organ name 'gallbladder'. It lies just below GB34, the He-sea point of the same meridian — a naming note, not a claim of effect.
- Korea's KMCRIC method locates it by tenderness rather than by a fixed number.
From traditional texts — not a claim of effect.
5Alternative location
Korea's KMCRIC database places it 1.5 B-cun below the front edge of the head of the fibula, in the tender hollow — slightly higher than the Chinese standard (2 B-cun below GB34).
