Lumbar lordosis is a common cause of chronic lumbar strain, which is caused by a change in the curvature of the lumbar spine due to poor lifestyle habits and work posture. Excessive flexion position will significantly reduce the contact area within the synovial joint, and the excessive pressure generated by prolonged continuous flexion will cause damage to the synovial joint, which will lead to lumbar retroflexion. For example, prolonged ambulation, head down to play cell phones, often bending work, housework, long-distance driving, may cause chronic spasm of the lumbar muscles, when the lumbar muscles will straighten the spine, the original physiological lumbar convexity will disappear into a straight line, or even backward protrusion, resulting in excessive stretching of the muscles, fascia and ligaments of the lumbar region, causing obvious symptoms of lumbar pain. In addition, tumor disease or tuberculosis of the lumbar region may also cause this phenomenon. Avoid bad working and living habits, avoid being sedentary, and sleep on a hard bed during treatment. Symptomatic treatment with non-steroidal anti-inflammatory drugs, including celecoxib and meloxicam, or eperisone hydrochloride may be used to relieve muscle spasm.
