When the cervical spine is strained and traumatized, even a minor injury will result in bleeding and edema at the edge of the vertebral body, and these small hematomas will gradually ossify and form bone spurs. If the protruding bone spur occurs right at the site of the nerve root outlet, resulting in pressure on the spinal cord or nerve root, a series of symptoms will result. Therefore, a series of symptoms that appear to be unrelated to the cervical spine appear in patients, but are in essence caused by the cervical spine lesion that stimulates the corresponding nerve. Cervical spondylosis can cause the following disease symptoms: poor swallowing The upper end of the esophagus is adjacent to the sixth cervical vertebra, and hyperplasia in the sixth cervical vertebra can compress and irritate the esophagus, even causing inflammation and edema around the esophagus, thus creating a foreign body sensation when eating. Elevated blood pressure When there is misalignment or hyperplasia in the cervical spine, it will compress and stimulate the adjacent vertebral artery or cervical sympathetic ganglion, resulting in spasm of the vertebral artery and insufficient blood supply to the basilar artery, reflexively causing increased excitability of the vasomotor center and causing elevated blood pressure. Some patients with cervical spondylosis have stimulation and injury to the adjacent cervical sympathetic nerve, which is transmitted to the brain, resulting in increased excitability of the relevant nerve and slowing of peristalsis in the gastrointestinal tract of the internal organs innervated by it, resulting in abdominal distension and constipation. Tachycardia Cervical spondylosis triggers cardiac discomfort, which mainly occurs when the fourth nerve root is stimulated by cervical spine osteophytes. This is associated with a sudden change in the position of the neck.
