Vertigo is a sensory disorder in which you feel yourself or the objects in your surroundings rotating or turning, often accompanied by nausea, vomiting and tinnitus. Some of them can be relieved by themselves, while some of them are light and heavy, repeatedly, which seriously affects work, study and life, and some of them cannot be relieved continuously and even develop further to endanger life. The common causes of vertigo are: 1. Systemic vertigo: a. Central vertigo: common causes are insufficient blood supply to vertebrobasilar artery, cerebral infarction, cerebral hemorrhage, brain tumor, etc. b. Peripheral vertigo: common causes are Meniere’s disease, vestibular neuronitis, positional vertigo, otitis media, etc. 2.
