For patients with lumbar muscle strain, cupping is useful. Because lumbar muscle strain is mainly caused by excessive force and strain on the lumbar muscles, coupled with the weakening of muscle relaxation caused by cold, there will be obvious wrinkling, stiffness, soreness and pain on both sides of the lumbar muscles, and the patient’s symptoms will be significantly aggravated after prolonged standing or prolonged sitting. Therefore, cupping of lumbar acupuncture points can be used to relieve muscle spasm and relieve the pain and soreness of the lumbar region. Cupping can also stimulate the acupuncture points and promote blood circulation in the lumbar region, which can help to reduce the edema of muscle cells caused by lumbar muscle strain.
