Vertigo is having a sensation of spinning of either the surrounding or within oneself but physical movement does not exist.
It may be secondary to different causes that may be determined by numerous factors eg timing and duration, aggravating conditions or associated symptoms.
Central vertigo originates from the central nervous system (brainstem or cerebellum). It is uncommon but more serious and should be ruled out immediately.
Peripheral vertigo originates from the labyrinth or vestibular nerve.
