The main reason why a patient has lumbar pain after walking for a day is that the patient’s walking time is too long, which has caused fatigue damage to the muscles of the lumbar region, resulting in the normal excretion of acid in the muscles and the accumulation of lactic acid, which will produce pain. In addition, patients walking for a long time will also affect the operation of qi and blood in the lumbar region, causing the local muscles to be in a state of tension and contraction, resulting in qi stagnation and blood stasis in the lumbar region and obstruction of the meridians, which can also cause pain and swelling. Patients should be told to stop walking and rest in bed, or take a hot bath and supplement carbohydrates. They can also be treated with hot towel compresses or with tui-na techniques, such as pushing and massaging in the lumbar region.
