Cervical spondylosis causes dizziness and headache commonly in two types of cervical spondylosis, which are treated as follows: 1. Vertebral artery type cervical spondylosis, vertebral artery type cervical spondylosis refers to the compression of the vertebral artery by cervical spine osteophytes, which makes the vertebral artery narrow and deformed and reduces blood flow to the head, resulting in dizziness and headache. For vertebral artery type cervical spondylosis, surgical intervention is needed to remove the hyperplastic bone, reduce vascular compression, increase blood supply to the brain and improve headache and dizziness. 2. Cervical cervical spondylosis refers to tension, stiffness and rigidity of the neck muscles leading to poor local blood circulation, causing headache and dizziness. Cervical cervical spondylosis requires attention to posture changes in daily life, avoiding long periods of looking down at cell phones and computers, working with low head, the need for relief and adjustment after maintaining a posture for a long time, and the need for a comfortable pillow when sleeping. Cervical cervical spondylosis can be done with beneficial physical exercise, such as swimming, playing badminton, flying kites, etc. These physical activities are beneficial to cervical cervical spondylosis.
