Got asked to do “vestibular testing”

Anything to expect?

Im 2 months into my latest attack and got some leftover lightheadedness (gets worse when on screens)

And some pressure at my ear area

And they said that the Vestibular tests would cause me to be dizzy? And im kinda scared since my dizzyness has improved vastly over the two months and i dont want to trigger anything again as im scared its gonna be another two month ordeal
