Sudden vertigo for a few seconds may be caused by otoliths, which is a kind of peripheral vertigo caused by the detachment of the otoliths from the semicircular canals, also known clinically as benign positional vertigo, which usually lasts from a few seconds to one or two minutes in most cases, and can stop suddenly and recur repeatedly, or can occur several times a day or even tens of times a day, with each attack being associated with the rotation of the head position. If the dizziness is serious, symptomatic anti-dizziness treatment can be administered at the same time, and the drugs commonly used in clinical practice include vertigo stop and accompanying tadacip.
