The clicking sound when the neck is turned is usually not serious. This condition is mainly caused by bad living habits and working posture, such as prolonged head down, prolonged exposure to computer and cell phone, sleeping on a pillow that is too high and too soft, repeatedly turning the neck, repeatedly lowering and raising the head, these bad living habits and working posture will easily lead to repeated contraction and stretching of the joint capsule of the small joints of the cervical spine. These poor living habits and working postures can easily lead to repeated contraction and stretching of the joint capsule of the small joints of the cervical spine, resulting in local sterile inflammation and joint capsule relaxation. The articular cartilage of the small joints of the cervical spine will be repeatedly rubbed, resulting in a clicking sound during rotation. These bad habits also tend to lead to accelerated degenerative changes in the cervical spine, such as cervical osteophytes, small joint dysfunction, cervical disc herniation, etc., which can lead to different degrees and types of cervical spondylosis and even neurological dysfunction over time.
