Hi Broken Wings,
Thanks so much for the welcome, the support, and the info.! I appreciate it a lot.
As far as the Sitting vs. Standing issue - I think you're talking about BPPV (Positional Vertigo). The ENT tested me for that when I was in his office the other day, and he said my eyes show no nystagmus (jumping, twitching, etc...) and I'm actually very "steady" when moving backwards from sitting to lying down and at the same time rotating my head to one side or the other. I don't know why it seems to hit when I'm mostly sitting, but then again that's where most of my time is spent, so it may be coincidental. Maybe I've just been lucky that it hasn't hit too badly when I am standing up! LOL
I'm honestly a jumble of emotions and thoughts right now as I try to figure all of this out. I'm trying not to worry as I've got a few weeks before my neuro appointment. I wish I could find anything on the 'net where someone described feeling like I do, but the results from searches of "feels like brain is moving" or the like usually bring me to info. about concussions and the brain literally moving!
Anyway, thanks so much for the reply and the suggestions. I've been reading through various sections here and there are many things I can relate to that people are dealing with - whether it's due to my possible neuro issues or not! I need to remind myself that neuros study this stuff in depth for DECADES and still don't have all the answers so I need to be patient while I'm trying to figure this out - and I don't have the benefit of that education, and diagnostics to eliminate some stuff I read about.
I'm starting to ramble a bit now, so I'll say goodbye for now. I have some time to read through some of the other sections this afternoon, so I'm pretty sure I'll be posting stuff around the site today.
Thanks again,
