This is second hand information so if you're going to use it take it for what it's worth. My husband talked to somebody in an assisted living facility, they said that people that get vertigo use a palm sander held against the ear with good results. So I guess you put a washcloth against your ear and then you put a palm sander running against your ear for a short period of time. Vertigo resolves itself. Everybody that tried it at the home home had resolved the vertigo

Vertigo and handheld palm sander
I suffered a series of episodes of vertigo due to acoustic trauma that damaged my vestibular organs. In the course of time I recovered from that. I would never ever do something like this nor would I recommend it to others.
There is more than one way vertigo can occur - Ménière's disease, BPPV, acoustic trauma, and Parkinson's caused impairment of the associated nerves. The vibration might help for something like BPPV, but can also cause damage and aggravate the problem if it is due to one of the other causes.
For a while my husband was getting vertigo regularly. He was doing stuff that was really reserved for a way younger men. Little crystals in his ear moved out of its place and that's what caused his vertigo. He used the Epley maneuver many times.
My physio completely cured my vertigo with a few simple movements called the Epley maneuver. Magic.
