Vertigo: Most of them are caused by pathological factors. 1. Benign paroxysmal positional vertigo: It is related to the change of head position, if there is obvious dizziness when doing head turning, it is usually benign paroxysmal positional vertigo, usually you need to go to the ENT department and improve the vertigo through manual reset after perfecting the related examination. 2. Vascular stenosis: There are risk factors such as hypertension and diabetes in the past and there is vascular stenosis.
