When suffering from cervical spondylosis often causes symptoms of head pain, mainly due to the following two types of cervical spondylosis: First, the more common is sympathetic cervical spondylosis. When sympathetic cervical spondylosis is produced, the function of sympathetic nerves will be disrupted, which will easily lead to head symptoms, eye, ear, nose and throat symptoms, cardiovascular system symptoms and symptoms of other systems. Patients will show dizziness, headache, vertigo, vomiting, etc. when nerve damage to the head is caused. Second, the headache caused by cervical spondylosis may also be caused by vertebral artery type cervical spondylosis. Because the formation of vertebral artery type cervical spondylosis will lead to a significant decrease in blood supply to the brain, thus triggering the symptoms of inadequate blood supply to the vertebrobasilar artery, which will eventually lead to headaches.
