Vertigo...wow, I didn't see that coming.

I dealt with it after suffering a concussion, mine was fairly mild, but still debilitating. Yote mentioned a simple treatment that worked for me, can’t remember what it's called but your doctor should have knowledge and access to the procedure. Unless of course you have tried it already and it doesn't help.
I do hope you are able to find relief from this condition as soon as possible, knowing how bad it was for me.
