About Hand San Li: Hand San Li is very commonly used in clinical practice and is very effective, but the prerequisite is that (1) the point should be taken accurately and the needle should feel strong; if there is no strong needle feeling, the efficacy is bound to be compromised. (2) When taking the points, first press with your fingers on the hand three li and its surrounding areas to find pressure points, sometimes there are more than one pressure point, choose the most painful point to stab; sometimes the most painful part is not the part of the hand three li as stated in the textbook, then also choose the most painful part. (3) It is better to lose its point than its meridian. 1. Knee pain: Hand San Li is good for many kinds of knee pain. Example 1: A male, about 50 years old, with intermittent pain in the left knee joint for many years; now the joint is stiff and painful, and it is painful to walk on level ground, and even painful to go up and down stairs or to bear weight; the appearance of the joint is normal, with pressure pain around the small head of the fibula, and no abnormality in the rest. He was instructed to lie on his back and needle the ipsilateral hand three li, the needle felt strong and felt the joint relaxed. The patient was asked to move the joint on the floor, and there was no pain and stiffness. Asked not to stand for a long time, do not bear weight, keep warm. 2, knee joint rat: joint rat is a more special case of joint disease. When walking, the patient will suddenly feel that the joint is stuck by something, all of a sudden was “fixed” like, can not move. This is because when a joint is damaged, the dislodged free body can change its position in the joint cavity due to joint movement, and move around in the joint like a mouse, so the intra-articular free body is also known as a joint rat. It is most common in the knee joint. Acupuncture of the hand three li has good effect on this. Example 1: Female, fat, with left knee pain for more than 10 years, with variable pain location, either left or right, accompanied by joint swelling, slightly high local temperature, frequent joint strangulation during walking, and abnormal pain; the hospital recommended surgery. After 5 times of treatment, the patient went on vacation. 3. Acute lumbar sprain: Case 1: male, stepped off the stairs and sprained his lumbar area for one day; the right side of the lumbar muscles were stiff and painful, and movement was limited; a cord was palpable at 3-4 inches from the spinous process of the fifth lumbar vertebra, and pressure pain was evident; Hand San Li, Cheng Shan, and Lumbar Pain points were taken, and the pain was relieved by 70% with local divine light irradiation. Example 2: This is a repeat patient. During acupuncture, the patient was in a prone position with both hands crossed under the jaw; this position was maintained for about 20 minutes. At the end of the treatment, when the patient got up (in the prone position), he suddenly felt pain in the left lumbar region, and the pain was worse when he turned around; its location was beyond the second line of the bladder meridian, about level with the fourth lumbar vertebra; taking the hand three li, the needle sensation was obvious, and the left lumbar region disappeared; the patient got out of bed and moved around freely. A few days later, the patient was re-examined and complained that the lumbar region was as usual and no further pain occurred. 4, chronic lumbar muscle strain and other chronic lumbar pain caused by various reasons also have very good curative effect. 5, facial diseases: Hand Yangming Large Intestine meridian comes out of the absence of basin, follows the neck, goes through the cheek, goes to the upper lip and ends at the contralateral Yingxiang point.
