Lumbar scoliosis can cause pain in the lower back. Because after the lumbar spine is scoliosis, it will lead to excessive strain on the musculofascia of the lumbar side, which will cause myofascia, inflammatory edema and spasm, and will cause pain in the lumbar area. After the lumbar vertebrae are scoliosis, it will lead to excessive compression of the vertebral body on the bent side, which will cause bone degeneration and hyperplasia. This proliferated bone will stimulate the surrounding soft tissues and cause pain in the lumbar region. After the lumbar scoliosis, it is also easy to cause the intervertebral discs to be overly squeezed, causing the rupture of the intervertebral disc fibrous ring, and the internal nucleus pulposus will protrude along the ruptured fibrous ring, causing pressure on the spinal cord or nerve roots in the spinal canal, which will also lead to lumbar pain. In severe cases, it may also cause radiating pain in the buttocks and legs.
