There are many causes of calf soreness, commonly due to sports injuries, such as climbing for hours in patients who normally exercise less, or suddenly increasing the amount of exercise in patients who normally exercise regularly. The factors affecting the acupuncture points for sore calves include: 1. local acupuncture points, needling the painful area can improve the soreness, and important acupuncture points in the calf include Yanglingquan, Chengshan point, and Xuanzhong point, which are used more frequently; 2. distal acupuncture points and cross-acupuncture points, choosing the points on the opposite upper limb such as Hand Sanli.
