①Lower back pain: the pain can be aggravated when the patient bends over, walks, coughs, sneezes or strains to defecate. ②Lumbar posture change: such as lateral bending deformity, some convex to the healthy side, some convex to the diseased side, lumbar activities in all directions are restricted to varying degrees. ③Pressure pain point: there is a limited pressure pain point next to the spinous process of lumbar vertebrae, which is equivalent to the nerve root pressure site. When pressure or percussion is applied to this area, the pain radiates to the lower leg as well. ④X-ray radiography can understand the situation of lumbar spine osteophytes, and CT and MR examination of the lumbar spine can make a clear diagnosis and clarify the direction of disc protrusion and the relationship with nerves.
