This happened to me last year around June-July. All of a sudden, if I would turn over in bed (especially to my left side), the room would spin horribly. I only stayed around for about a week. I don't have hardly any problem when I'm upright......just when I'm laying down.
I don't have any congestion and my sinuses seem clear (although I have had some forehead pressure and more headaches that usual).
I'm drinking alot of water. My ears aren't congested either.
Please don't tell me I'm working on Meniere's, 'cause I just won't hear of it!
I just find it very strange that it only happens when I lay down.
(I had a huge work-up for dizziness a couple years ago....had MRI scans of my brain and other tests and all was normal). I do have pulsatile tinnitus all the time, but I'm thinking its my funky fibromyalgia.
P.S. I do use a cpap with nasal mask, but I don't think that's a problem.
Oh.....and I'm 128 years old. At least that's what I feel like.
