Dizziness and brain swelling are more common in patients with cervical spondylosis, generally because of the following two reasons: i. Patients with vertebral artery type cervical spondylosis are prone to this condition because cervical spondylosis stimulates and compresses the blood vessels leading to the skull, and direct compression causes inadequate blood supply. The herniated nucleus pulposus of the cervical spine stimulates the spinal cord or external growths that stimulate the nerves around the blood vessels leading to the skull can cause indirect constriction and spasm of the blood vessels causing inadequate blood supply. Insufficient blood supply to the intracranial blood vessels can easily cause ischemia in the head, resulting in pain, soreness, dizziness, brain swelling, and dizziness in the back of the head. Second, sympathetic cervical spondylosis can cause stimulation of the plant nerve function, which can easily produce dizziness, blurred vision, sweating, and panic, and can also cause dizziness and brain swelling. This condition is also more common and requires avoidance of poor posture of the neck, application of blood activating and nourishing drugs, and symptomatic treatment after clear examination.
