我今年40岁,平时身体很好,也很喜欢锻炼,从去年以来,却经常出现头晕,经检查发现血压高达165/105毫米汞柱,就医多次也不见改善。后才查出,我的第一颈椎出现错位,导致椎动脉受压迫,所以常常头晕。请问,为什么会出现这种情况呢? I am 40 years old and am usually in good health. I also like to exercise. Since last year, I often feel dizzy. After examination, my blood pressure has been as high as 165/105 mm Hg. After finding out, my first cervical dislocation, resulting in compression of the vertebral artery, so often dizzy. Excuse me, why does this happen?
