Finally went to er for dizziness and was diagnosed with benign positional vertigo ? whats this is this serious>?

Inner ear: This is a common condition where a tiny concretion gets loose in the labyrinths of the inner ear. This displaced loose body makes the brain feel that you or the room is moving when they aren't. It's not a serious disorder but does cause vertigo and nausea which medicines like Meclizine help but in stubborn cases an otolaryngologist can perform maneuvers that may clear up or improve the symptoms.

BPPV: Benign paroxysmal positional vertigo (bppv) is one of the most common causes of dizziness. Often treatment with antihistamines and decongestants can be curative. On occasion, physical therapy with a certified vestibular rehab specialist may be required to correct any issues that could cause the bppv in your inner ear. Best wishes.

JustALabel - Depends: Benign=guessed/judged to not be serious/progressive/indicative of advanced-disease. Positional=seems to relate to, vary with body position (presumably in relation to gravity). Vertigo=person reports sensation of not being stable, spinning, whirling, etc. Like all diagnoses, just a label; no clear relation with either causes or outcome, especially over time. Plus varies with individual over time.

BPPV: Benign paroxysmal positional vertigo causes short episodes of intense dizziness (vertigo) when you move your head in certain directions. Vertigo is the sensation that you or your surroundings are moving. Benign paroxysmal positional vertigo is thought to be caused by tiny solid fragments (otoconia) in the inner ear labyrinth. In many cases the condition gets better on its own after several weeks.http://patient.info/health/benign-paroxysmal-positional-vertigo-leaflet
