Spondylosis is a disease that occurs when the bones, intervertebral discs, muscles and ligaments of the spine change and stimulate the nerve roots of the spinal cord, mainly including cervical spondylosis and cervical disc herniation in the cervical spine, lumbar disc herniation and lumbar spinal stenosis in the lumbar spine, and thoracic spinal stenosis in the thoracic spine. From the neck down the spine is the thoracic spine, then down the lumbar spine, and then down the sacral spine, and diseases of the entire spine are called spondylosis. Spondylosis is a larger category, and generally the spine includes the cervical, thoracic, lumbar and caudal spine, and pain symptoms can occur throughout the entire range from the cervical spine to the caudal spine. Like cervical spine pathology will appear neck and shoulder pain, if there is nerve compression, there is pain and numbness in both upper limbs. If a problem occurs in the thoracic spine, back pain appears. If there is a problem in the lumbar spine, low back pain and lumbago appear. If there is nerve compression, lower limb pain, numbness or not walking far appears. If there is a problem with the caudal spine, there is tailbone pain, that is, pain in the caudal spine when sitting. Some spinal diseases also have nocturnal pain, that is, pain gradually appears at night when sleeping, and some people also have stiffness, such as stiffness of the spine can not be bent and limited movement.
