I have been experiencing vertigo off and on for a year. I have a Dr. Appointment but I always have to ask Dr. Google. This is what Doctor Google told me:
This is what BPPV is:
“Benign paroxysmal positional vertigo (BPPV) is a disorder arising from a problem in the inner ear.[3] Symptoms are repeated, brief periods of vertigo with movement, that is, of a spinning sensation upon changes in the position of the head. This can occur with turning in bed or changing position.[3] Each episode of vertigo typically lasts less than one minute. Nausea is commonly associated.[6] BPPV is one of the most common causes of vertigo.
BPPV can result from a head injury or simply occur among those who are older.[3] A specific cause is often not found. The underlying mechanism involves a small calcified otolith moving around loose in the inner ear.”
