Sunshine point is located in the depression between the joints between the three or four metacarpal bones on the dorsal side of the hand, and is more effective in treating lumbago. Sunshine point is an experienced point for the treatment of lumbar pain, and has a certain pain-relieving effect on lumbar pain caused by acute lumbar sprain, cold-dampness lumbar pain, and lumbar muscle strain. It is located in the depression between the joints between the three or four metacarpal bones on the dorsal side of the hand, in the middle of two points for lumbago. It should be noted that the effect of a single point in treating the disease may be insufficient, and it is generally necessary to combine other points to treat lumbar pain synergistically, such as Huizhong point, Chengshan point, etc. The point is located in the rouge fossa. The point is located in the center of the rouge fossa, at the midpoint of the transverse stripe, in the middle of the biceps femoris tendon and semitendinosus tendon. Chengshan point is located in the posterior region of the calf, at the corner of the two muscle bellies and tendons of the gastrocnemius muscle. Sunshine points must be operated by a professional acupuncturist when treating diseases, and must not be used by oneself to avoid causing damage to the organism.
