Straightening of the physiological curvature of the cervical spine may affect blood pressure, but not absolutely. Straightening of the physiological curvature of the cervical spine will accelerate the degeneration of the cervical spine and cause changes such as cervical disc herniation, and when the condition develops further, it will cause compression of the spinal cord, nerves, blood vessels, and so on. Compression of the vertebral artery or sympathetic nerves can cause peripheral vasoconstriction and accelerated heart rate, which can lead to abnormal blood pressure. The changes in blood pressure caused by cervical spine physiological curvature straightening have certain characteristics. Generally, the blood pressure will change when symptoms such as neck pain, headache and dizziness occur, and will gradually stabilize after the neck symptoms are relieved. Patients with cervical spine physiological curvature straightening should develop good living habits, avoid prolonged low head, and actively carry out neck functional exercises. If there are symptoms such as neck pain and discomfort, suspected cervical vertebrae physiological curvature straightening, should go to the hospital in time for further diagnosis and treatment.
