Contracting arm sinew with achy pain, along with inability to eat food and lack of consciousness
The practitioner presses and fixes the knotted muscle with his left thumb and needles the muscle. When the needle reaches the damaged muscle, there will be unbearable pain. This is the heaven response point. Following the pain and needling it will produce great effect. If there is no effect, repeat it. Needling the whole acupuncture points in meridians could not produce better result than this. 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.
