1. The increase and decrease of blood pressure are synchronized with the symptoms of cervical spine disease attack. Blood pressure rises when the patient has symptoms of cervical spondylosis such as pain at the back of the neck, headache or dizziness; when the head and neck symptoms are relieved, blood pressure also decreases. This feature is especially obvious in the early stage of the disease; with the prolongation of the disease, this phenomenon gradually decreases. 2. Hypotension or fluctuations in blood pressure may occur for a considerable period of time before the onset of hypertension. Patients show symptoms such as dizziness, lightheadedness, memory loss, and general weakness. 3, their own hypertension is mostly insensitive to antihypertensive drugs, while the treatment of cervical spondylosis is effective. With the improvement of cervical spondylosis condition, blood pressure basically tends to stabilize. 4, in the 24-hour ambulatory blood pressure observation, in traction, manipulation treatment of cervical spondylosis, the patient’s blood pressure can drop 20-30mmHg, and the blood pressure will rise again in the interval of treatment. 5, hypertension is related to the degree of vertebral instability or subluxation, that is, the greater the vertebral subluxation, the more serious the hypertension, but it is not necessarily completely consistent with the degree of osteophytes. Because to some extent, osteophytes or ossification of the anterior longitudinal ligament enhances the stability of the spine and reduces the impact of abnormal organism proliferation on local neurovascularity. For those with long-term hypertension, unsatisfactory blood pressure control with medication, no family history of hypertension in the family, and symptomatic episodes with characteristics similar to cervical spondylosis, it is advisable to take cervical spine x-ray or cervical spine CT film first to exclude cervical spondylotic hypertension.
