yeah see the issue is, I never have vertigo in any other instance. Ive
never had a problem with balance or dizziness, in fact I have rather
good balance. So this is either a vertigo issue that my inner ear is
sensitive to under extreme pressure instances, or something entirely
else, because outside of this very specific plane scenario, I never
have gotten that feeling before, or even a vertigo of a much milder
form. I can turn my head quickly a million times, get out of bed
quickly, stand up quickly etc... and I never get dizzy or have any
symptoms of anything else.

Its leading me to belive that after 25 years of major sinus infections
and awful allergies, my inner ear area may have gotten sensitive (or
possibly even scarred) and is now hyper sensitive to the pressure and
thus causes vertigo, or its a cardiac thing which is unlikely being
that I have no other symptoms and im 25, but hey, I've seen more
surprising things in my life (lets hope I don't tack this on to the
list).
