Recently seemed to accompany one of my long hard flares. I have mentioned to the docx, they check all kind of things that come back normal or almost. I know it was worse when I was taking Lyrica. Like being on a boat...but medical reason. Then ent says it is all caused by muscles in neck being so tight with pain. That It is the fibro and we need specially supportive pillows to sleep on... I am still going to dox. but this it why I have vertigo, and a list of others...fibro...? Who knows.
I am not sure if my symtoms are like yours, but they seemed that they might..
Turning can be difficult and I have to close my eyes (especially when working in kitchen). May have to grab to stable my vertical balance. I seem more sensitive to bright busy patterns and eyes tire faster when watching tv...
Hope it starts to get better or that they start to give you answers and help.
