Vertigo caused by ear diseases (mainly inner ear diseases) is collectively called otogenic vertigo. The common ear diseases that cause vertigo include Meniere’s disease, vaginitis, vagus trauma, vagus membrane rupture, benign positional vertigo, ototoxic drug poisoning, vestibular blood supply disorder, motion sickness, etc. Otogenic vertigo has the following characteristics: 1. It often starts suddenly, lasts for different periods of time, and can be relieved naturally, but often recurs. 2. Patients feel themselves or external objects rotating, and the vertigo is intense, often accompanied by tinnitus, deafness, nausea, vomiting, cold sweat, pallor, drop in blood pressure and other vegetative symptoms, but there is no impairment of consciousness or other cranial nerve symptoms. 3. The episodes usually have horizontal or rotational spontaneous eye tremor of varying intensity, with fast and slow phase and fixed direction.
