Patients with back pain that occurs as a result of external force or chronic strain can be given topical plasters. The specific site of external plastering, first, should be given with the pain point clear site as the center of external plastering. If the patient’s pressure point is not clear, or the pressure pain is extensive, the plaster should be given to the swollen area as the center and changed every 24-48 hours. When applying the plaster, the patient should be instructed to minimize the weight-bearing activities of the lumbar region and should rest in bed to avoid aggravating the condition, and other auxiliary treatments can also be used, such as taking oral Shujin Wanhua Blood Tablet, Daxuodan and Danshen Tablet, which can relieve the patient’s pain.
