Neck swaying from side to side hear creaking sound, may be caused by normal physiological reasons, such as long time to maintain a low position, frequent activities of the neck, etc.. It may also be caused by certain pathological factors, such as cervical spondylosis, osteophytes and so on. 1. Physiological reasons: prolonged head-down or frequent neck activities can lead to muscle tension and spasm around the cervical spine, which can cause repeated extrusion and friction between the joint capsule or ligaments in the process of movement, resulting in popping sounds. Most patients can have no obvious symptoms, which is a physiological phenomenon. 2. Cervical spondylosis: Cervical spondylosis is a degenerative disease, due to the wear and tear of the cervical joint surfaces, when twisting the neck will increase the cervical joints, tendons and ligaments of the cervical spine angle of movement, resulting in rattling. 3. Osteomalacia: Osteomalacia is mostly seen in the elderly, due to hyperplasia of the cervical spine, resulting in thickening of the ligaments or thickening of the joint capsule, which can easily cause interlocking between the joint synapses, and therefore, corresponding rattling sounds will occur during neck activities. If the symptoms of frequent neck activity sound, in the exclusion of physiological reasons, patients should go to the hospital in a timely manner to clarify the cause of the disease. Usually should pay attention to sitting and standing posture, avoid long time to keep the same action, reduce the pressure of cervical vertebrae.
