Acupuncture can treat sore and swollen legs. Sore and swollen legs are mainly caused by localized stagnation of qi and blood in the meridians and channels, and if the meridians and channels are not clear, then the qi and blood flow will be blocked, which is mainly manifested as pain, numbness, and so on. Acupuncture and moxibustion treatment is mainly through the meridian acupoints and the role of acupuncture and moxibustion techniques, so that the meridians and channels are smooth, to promote the normal operation of qi and blood. For example, acupuncture points such as Chengshan and Yanglingquan on the calf can be used to treat the condition. However, acupuncture should be performed after diagnosis by a physician. During treatment, keep warm and do not engage in strenuous exercise to avoid unnecessary damage. Acupuncture and moxibustion are risky and are not recommended to be performed by patients themselves. It is recommended to go to the hospital in time when you are not feeling well, and under the guidance of the doctor for standardized treatment.
