There are many reasons for cervical spine ringing, mostly due to calcification of cervical ligaments, degenerative changes of cervical vertebrae, dislocation of cervical joints, and escape of intra-articular gases, etc. It can be avoided if there is no abnormal sensation, but when accompanied by pain and other symptoms, it is necessary to consult a doctor in a timely manner. 1. Calcification of cervical ligaments: Calcification of cervical ligaments can be caused by long-term improper posture and strain injury, etc. When the cervical ligaments become hard and calcified during neck activities, rattling sound can be heard when the ligaments are rubbing against the cervical vertebrae. 2. Degenerative changes of the cervical spine: degeneration of the cervical spine can occur in the cervical spine articular surface cartilage wear, deformation, etc., in the neck activities, the friction of the articular surface can lead to cervical vertebrae ringing. 3. Displacement of joints: prolonged bowing of the head and improper posture can lead to displacement of the joints of the cervical spine, and the reset of the joints can cause rattling during activities. 4. Gas escape: under normal circumstances, there is synovial fluid between the joints of the cervical spine, and there is a certain amount of gas inside, when the joints are moving, the synovial fluid inside is squeezed, and the gas escapes and rattles. It is recommended that the patient go to the hospital for examination in order to clarify the cause of the disease, and if necessary, the professional physician will give appropriate treatment according to the condition.
