Hi guys,
I have a bunch of other issues however I have had this from my teenage years that no one could find a diagnosis for, I know that a lot of people on here are intelligent and might even just have a suggestion of what it could be...

I woke up one day with feeling of fluid in my head I could move my head and feel it swish around, I have dizziness if I get up from laying and it's worse when I get up after laying down so sometimes it feels like it moves from the side of head to top of forehead ...

I feel it puts my off balance and makes my head feel super heavy..

ENT ruled out what they could on ear exam but said I was dizzy with a table test

MRI is clean..

No sinus issues..

Any ideas?

I can hear heart pounding in my ear at times not sure if that's connected.l
Any ideas?
