Hello My mother has been suffering from Vertigo for about 12 years, she takes Vertin tabs during the episodes... once in 2 or 3 months, it subsides in couple of days usually Recently, after the head spinning subsided, after 2 days she continued to have the spinning feeling when she is lying on the bed and turns to the right. I thought the symptom seems like BBPV or Positional Vertigo, what is the treatment u suggest?
