Appropriate small-range rotation of the neck is usually not harmful to the cervical spine, but avoid violent, large-range rotation of the neck, so as not to cause damage to the cervical spine. If there is no history of cervical spondylosis, you can rotate your neck in small increments to pull and relax your neck muscles after working at the desk for a long period of time or maintaining a posture, which is usually harmless to your neck. If you suffer from more serious spinal cord cervical spondylosis, rotating your neck violently may compress your spinal cord, which may cause pain in your neck and dizziness and other symptoms. Normally, you can rotate your neck in a small range and slowly, which can relax your neck properly and help to relieve neck discomfort. If you experience any discomfort during the process of rotating your neck, you should consult a doctor for examination in a timely manner.
