Lumbar pain all the time may be caused by long-term wrong posture, environmental stimuli and other physiological factors, or it may be caused by lumbar disc herniation, lumbar spondylolisthesis and other pathological reasons. 1. Physiological factors: long-term stooping labor or prolonged standing and sitting may lead to lumbar myofascial edema, stiffness, impaired local blood circulation, accumulation of metabolic products, resulting in aseptic inflammation, resulting in pain symptoms; prolonged exposure to cold and damp environment will lead to lumbar blood slowing, myofascial spasm, and the above symptoms may also occur. 2. Pathological causes: degenerative lesions of lumbar vertebrae lead to lumbar disc herniation, which may result in the formation of vertebral body osteophytes, calcification of ligamentum flavum, narrowing of the intervertebral space, etc., resulting in compensation of the myofascia, compression of the nerves, etc., and the emergence of pain symptoms. Based on the symptoms of constant back pain alone, sometimes the cause cannot be accurately determined, and it is necessary to combine the characteristics of the medical history and other examination results to make an accurate judgment, and it is recommended to clarify the cause of the disease under the guidance of a doctor.
