Most cervical curvature changes are seen in cervical curvature straightening. If there is dizziness, most of it is seen in insufficient blood supply to the basilar artery caused by cervical compression, and also in dizziness caused by abnormal sympathetic excitability, which can be improved by taking oral flunarizine hydrochloride capsules and betahistine tablets. It has a very good effect on vasodilatation and can also improve the blood supply to the base of the brain, which can relieve dizziness. For increased sympathetic excitability, sympathetic excitability inhibiting drugs can be applied under the guidance of a line doctor.
