If the patient’s back gets cold, it can cause pain in the back area. This will cause the muscles in the back to contract, tense and spasm, which will lead to an increase in pressure in the muscles and produce a large amount of inflammatory factors that will stimulate the surrounding nerves and cause pain in the back, and also affect the patient’s normal activities. In addition, if the patient’s back area gets cold, it will also affect the flow of qi and blood in the back area, resulting in localized qi stagnation and blood stasis, and there will be meridian obstruction, which will also produce painful manifestations. When this clinical phenomenon occurs, patients should be told to stay away from wet and cold environments and pay attention to the warmth of the back area, which can be treated with hot towels, physiotherapy and baking.
