Once one side of the cervical artery is compressed, especially the joints between the vertebrae of the cervical spine form obvious bone hyperplasia, the narrowing of the vertebral space will stimulate or compress the vertebral artery, or stimulate the sympathetic nerve of the neck, which reflexively causes the vertebral artery to spasm, which will lead to the symptoms of insufficient cerebral blood supply, or cause insufficient arterial blood supply in the ear, The symptoms of dizziness, headache and dizziness are relieved after a break, and the symptoms become worse after overwork and long time bowing. When suddenly turning back, turning back, or bowing or raising your head, a temporary fainting may occur. After fainting, you can quickly recover consciousness without any discomfort, It is very common for this vertebral artery type of cervical spondylosis to cause symptoms of insufficient cerebral blood supply.
