Sympathetic cervical spondylosis generally does not cause motion sickness. The main causes of motion sickness include motion sickness and vertebral artery cervical spondylosis. 1. Motion sickness: Most of the patients with motion sickness are caused by motion sickness. Motion sickness refers to the variable-speed motion in the form of swaying or rotating that occurs during the movement of cars, ships and other means of transportation, which stimulates the vestibular system of the human body and gives rise to the symptom of vertigo. While sympathetic cervical spondylosis may also cause dizziness, it is fundamentally different from motion sickness caused by motion sickness. 2. Vertebral artery-type carotid disease: Vertebral artery-type carotid disease in the classification of carotid disease may also lead to symptoms of motion sickness. Vertebral artery-type carotid spondylosis will lead to the patient’s vertebral artery pressure, causing insufficient blood supply to the brain, and when stimulated by the pressure of variable-speed movement, the symptoms will worsen, and the symptoms of motion sickness may occur. If the symptoms are not relieved after lifestyle modification, you should consult a doctor in time to clarify the cause of the disease and treat it under the guidance of a doctor.
