Good for you Tony!
When I moved to Florida, I noticed something resembling vertigo when I was flying.......seemed okay riding the motorbike, but became a bit disoriented while spinning around....
That, combined with some lingering effects of GBS, had me concerned.....I mentioned it to a VA MD, who scheduled an inner ear test ....
That MD said that I seemed normal (!!!), but that I might be experiencing allergies and suggested that I take a Xertec (sp) in the morning and an allerest in the evening....sure enough, things got better.....not 100%, but I'm old.
Best advice is to see a doctor....
Have fun!
