Cervical spine hypertension can be diagnosed through medical history, clinical manifestations and auxiliary examination. 1. Medical history: the patient has cervical spondylosis and other cervical spine related diseases, high blood pressure, ineffective in taking antihypertensive drugs, the general course of the disease is more than one year, the blood pressure tends to be normalized after reasonable treatment of cervical spondylosis, and the patient has the habit of working for a long time with his/her head lowered. 2. Clinical manifestations: blood pressure changes are correlated with the onset of cervical spondylosis symptoms; blood pressure rises when headache, dizziness, or neck and shoulder pain occurs, and then falls when the symptoms are relieved. This feature is especially obvious in the early stage of the disease, but with the prolongation of the course of the disease, its characteristics gradually weakened. 3. Auxiliary examination: X-ray clearly indicates that there are cervical vertebral osteophytes, cervical vertebral degenerative disease, subluxation, etc. CT and magnetic resonance indicate that the discs from the 2nd to the 7th cervical vertebrae are bulging or protruding, which compress the sympathetic nerves and vertebral arteries. It is recommended to consult a doctor in time when discomfort occurs, and do not take unauthorized treatment to avoid danger.
