A 9-year-old male, with no significant past medical history, presents to the office with dizziness over 3 days. He reports sudden onset of a “queasy” feeling at bedtime. He then awoke from sleep with a “spinning” sensation, vomited, and felt off balance. Family reports that he looked pale during the episode and was unable to open his eyes due to the spinning sensation. Family was unable to evaluate for nystagmus.
