Clinically, the patient’s back pain is related to heavy dampness, because if the patient is in a damp and cold environment for a long time, the cold in the back will affect the normal operation of the qi and blood in the back, resulting in localized qi stagnation and blood stasis, meridian obstruction, and the patient will experience back pain. In addition, when the patient’s lumbar region gets cold, the metabolism of lactic acid in the muscles will be impaired, resulting in lactic acid accumulation, and the patient will also suffer from lumbar pain. If the patient suffers from fasciitis and bursitis in the lumbar region, the local condition can be aggravated after catching a cold, making the patient’s pain symptoms significantly worse. Therefore, the patient needs to keep the lumbar area warm after this condition, you can apply hot compresses or baking electricity, you can also use herbal fumigation and other methods to promote local blood circulation, can relieve the phenomenon of lumbar pain.
