“In general; Benign paroxysmal positional vertigo (BPPV) is an inner ear disorder. A person with BPPV experiences a sudden spinning sensation whenever they move their head. BPPV isn’t a sign of a serious problem. If it doesn’t disappear on its own within six weeks, a simple in-office procedure can help ease your symptoms.”
