LI4 (Hegu) is the web between thumb and index finger, commonly used on the traditional map for head and neck tension; avoided in pregnancy.
In 📝Acupressure the point is pressed in the fleshy web, toward the bone of the index finger. The traditional use is the map, not a claim to treat headache as a medical condition. Not used in pregnancy. Sharp, numb, or panicky sensation is a stop.
Clients feel a deep local ache, sometimes into the arm or head. Bruising is too much dose. Homework is the same point on their own hand, skipped if pregnant.
