Tinnitus Not Present When Sitting Straight Up with Back Slightly Tilted

Does anyone have a possibility of ear pressure/fullness/tinnitus/sensitivity to noise? If so, does anyone in this predicament notice an ease of these symptoms when sitting down head straight up and/or back tilted slight angle, but more or less sitting up right?

If so, what does that mean as far as conditions...

Currently, I may have ETD or cochlear hydrops combined with minor hyperacusis.

Anyways, it is interesting how the pressure does not get as bad when in this position. I would say when I am in a well air conditioned place it seems calmest also... and a place with not too heavy ambient noises in background.

I am going on almost two months of this with about 50% improvement from the beginning stages but the remnants can be frustrating and have made me hermit myself a bit... trying to figure this out and also be patient. (PS. been to 3 ENT's, prescribed nothing, mentioned the usual, use Flonase etc.)
