Vertigo is a specific type of dizziness resulting from medical problems usually associated with the inner ear or the vestibular nerve. It is not a fear of heights, which is classified as a phobia.
If you get vertigo on specific movements that last less than a minute, chances are you have BPPV or “Benign Paroxysmal Positional Vertigo”. This is the most common cause of vertigo and accounts for 1/3 of vestibular disorders (van Brevern 2007). Fortunately, it is usually very easily treated. The modified Epley maneuver is the most effective procedure for resolving symptoms with a 88% success rate after one treatment (Herdman, 2000). If you suspect you have BPPV, do not continue to suffer with these symptoms, contact a vestibular therapist who can treat you.
