There are many reasons for dizziness, such as cervical spondylosis, Meniere's disease, inner ear disease, cerebral blood supply deficiency, intracranial lesions, hypertension, hypotension, anemia, long-term insomnia, physical weakness after illness and so on. These will all lead to dizziness. I don't know what tests I went to the hospital to do, and whether I completely ruled out the inner ear labyrinth, vestibular nerve, brain stem and cerebellum lesions.
