I did not know that Dr. Cohen passed away. We have lost a wise and very compassionate voice for neuropathy and other medical concerns. Sigh...

As far as vertigo goes, I have had over the past 40+yrs several vertigo spells. 3 were severe with huge instability and the last one was just 2 months ago which was positional lying down in bed. I was dealing with that last one, and taurine was helping. But you know, my accident I tripped in the hall upstairs and
stumbled into an opposite wall rather hard (hurting my right side severely and getting 3 bad bleeding scrapes on my right elbow.) For some reason hitting my right side this way, and hitting the floor hard, stopped my vertigo instantly! It was a painful event to be sure but now I can lie on my left side in bed again.

I had a electronystagmagram in the late 70's which told me that the auditory nerve in my left ear was not working. But then I was not deaf in that ear as would be expected from that? A little hearing loss but not much, in reality. When I have had my vertigo attacks they always center on that ear. The specialist ENT back then said it was either due to an accident or head hit on that side, or the measles which is a common nerve viral culprit for the ear.

Today, tick borne illness could be added to the list of auditory nerve damage.
