Contracting arm sinew with achy pain, along with inability to eat food and lack of consciousness
There are points that respond to heaven energy.
The practitioner presses and fixes the knotted muscle with his left thumb and needles the muscle. When the acupuncture needle reaches the damaged muscle, there will be unbearable pain. This is the heaven response point.
Needling damaged muscle will produce immediate effect, but needling normal muscle will produce slow and little effect. You should pull the needle out and needle the damaged muscle.
