Intervertebral ligament injury: Intervertebral ligaments are richly distributed, which help to fix and stabilize the spinal structure and participate in the movement of the spine. When the ligaments between the vertebrae are injured due to trauma or sports, it can lead to localized coldness in the ligaments and the spine. 4. Ankylosing spondylitis: Ankylosing spondylitis is an autoimmune disease, which can lead to local immune response when it involves the spine, forming inflammatory foci, which can stimulate the spine and soft tissues to appear spinal cold discomfort.
