Walking requires not only the function of the muscles of the lower limbs to achieve, but also the muscles of the hip, waist, back, and even the shoulder to maintain a certain level of tension, to maintain a certain muscle strength, to maintain the shape of the body, and to ensure the stability of walking and movement. After walking for a long time, the muscles of the lower back are prone to strain or even injury, producing soreness and pain. The muscles of the lower extremities are in contraction and diastole intermittently when walking, while the muscles of the low back are continuously tense and maintain a certain muscle tone, making it easier for strain and injury to occur. Patients can reduce the amount of exercise, do not walk for a long time, while resting accordingly, local anti-inflammatory and analgesic drugs, blood circulation and blood stasis can be used, and physical therapy, such as hot compresses, baking electricity, etc. to relieve local strain and injury. After rest and symptomatic treatment, it can be significantly relieved in a week or so. If the symptoms are not relieved and pain appears in the lower back when walking, it is recommended to go to the hospital for detailed examination.
