It can be triggered  by looking down from a high place, or  by looking straight up at a high place  or tall object, but this alone does  not describe vertigo. True vertigo can  be triggered by almost any type of  movement (e.g. standing up, sitting  down, walking) or change in visual  perspective (e.g. squatting down,  walking up or down stairs, looking out  of the window of a moving car or  train).     Next       Prev       Home        End
