Many people come to the clinic because of spinal pain, including cervical vertebra, thoracic vertebra, lumbar vertebra and sacrococcygeal vertebra. What is spinal pain? In fact, it needs to be analyzed in combination with the anatomical structure of the spine. Spine includes bones, as well as muscles, ligaments, fasciae and soft tissues outside the bones, and inside the bones, including intervertebral discs, spinal nerves, etc. If these anatomical structures go wrong, spinal pain may be caused. For example, poor posture, such as sitting for a long time, standing for a long time, bending over, and lowering the head, can cause muscle strain and feel spinal pain. The other reason is that muscle strain is caused by cold, involvement, trauma, or excessive activity, or aseptic inflammation occurs in the muscle disc. Inflammation may cause vertebral fracture, and may also cause spinal pain. Because the protrusion of the intervertebral disc compresses the spinal nerve, it is also a common cause of spinal pain. Relatively rare cases, such as tumors, can also cause pain because of tumor metastasis to the spine at other locations. In addition to orthopedic problems, there are also some diseases in other departments, such as ankylosing spondylitis in the immunology department, which may cause sacroiliac joints, or even downward to upward, with gradually bamboo like changes, causing spinal pain. Therefore, only by combining the patient's medical history, clinical physical examination, and necessary auxiliary examinations, and comprehensive analysis and judgment, can we find out what causes spinal pain.
