Patients who often twist their necks will cause the small joints in the cervical spine to shift and reset to varying degrees when they twist their necks, and the ringing sound they hear is also from this, often deliberately making their necks twist will cause the joint capsule of the cervical synovial joints to become loose, which will cause the joint surface to lose its flat state and the gap between the joints to be too narrow in the long run, and even form osteophytes or sclerosis, etc. Seriously, this will cause intervertebral disc disease due to osteophytes, calcification and degeneration of the cervical spine. Osteomalacia, calcification and degeneration of the cervical spine cause intervertebral disc disease, such as cracks or even rupture of the fibrous ring. If the intervertebral disc compresses the nerve roots or the bony channels around the synovial joints compressing the nerve roots, it will cause radioactive pain or numbness in the upper limbs, and if the spinal cord is compressed, walking will become unstable.
