In recent years, the incidence of cervical spondylosis has been on the rise, especially in the group of brain workers. In daily life, if there are the following conditions, no abnormal findings by routine medical examination and no obvious efficacy after treatment, cervical spine pathology should be highly suspected to avoid delaying treatment. 1, heart disease Cervical heart syndrome: cervical spondylosis can cause compression of the lateral branch nerves of the C7-T1 segmental nerve, and cervical joint osteophytes can also stimulate sympathetic nerve fibers, causing symptoms in the heart. If you encounter heart disease of unknown cause, which is not effective by conventional treatment and the symptoms are related to head and neck activities, you should think of the possibility of cervical spondylosis and promptly take X-ray or CT examination to make a clear diagnosis. 2, hypertension Cervical hypertension: cervical spondylosis can cause an increase or decrease in blood pressure, of which the increase in blood pressure is more, so it is called “cervical hypertension. For patients whose blood pressure is not satisfactorily controlled by hypertension medication, especially those who do not have a family history of hypertension and whose symptoms have similar characteristics to cervical spondylosis, we should consider taking cervical spine X-ray or cervical spine CT scan or MRI to exclude cervical spondylosis caused by cervical spondylosis hypertension. 3. Dizziness and nausea Cervical vertigo: it is vertigo caused by insufficient blood supply to the brain due to spasm of the cervical blood vessels, especially the vertebral artery, caused by cervical spondylosis. It is often confused with otogenic vertigo, oculogenic vertigo or neurological vertigo. The most typical symptom is dizziness, and head and neck activities and posture changes can trigger or aggravate vertigo. 4.Pharyngeal discomfort Cervicogenic dysphagia: This kind of disease is due to rapid osteophyte growth of the lower cervical vertebrae and excessive bone superfluity, which compresses the esophagus immediately in front and causes stenosis due to inflammation and edema, and is easily misdiagnosed as esophageal disease in clinical practice. 5.Persistent headache Cervicogenic headache: headache caused by cervical-occipital lesion especially atlanto-axial joint, generally accompanied by vertigo symptoms, headache is common in the back of the occipital region, but can also appear in the temporal region of the head or forehead brow bone, in the clinical diagnosis is mostly tension headache or migraine, the incidence of women is significantly higher than that of men. 6. Visual changes Cervicogenic visual impairment: The main clinical manifestations are paroxysmal transient blindness, paroxysmal diplopia, or visual impairment such as reduced visual acuity, blurred vision, visual field defects, and blinking colors. It is often caused by abnormal anatomical position/anatomical structure of the cervical spine, cervical medulla, and diseases of the tissues surrounding the cervical spine. Most patients have symptoms of cervical spondylosis or are accompanied by cervical dizziness and lightheadedness.
