What kind of symptoms are you showing during these episodes? Did you have any sort of accident before the vertigo or whiplashes etc at any point in your life?
I saw a Neurologist, ENT, balance therapist, acupuncturist, Cranio-sacral therapist, Neurotologist, and Otologist (this is probably the dr they are referring to) and had NO relief.
I have now found lots of relief with Atlas Orthogonal adjustments and am very hopeful for my long-term improvements.
Best wishes :-)
