Postural hypotension and deafness?

I've been deaf in left for about 15 yrs and meniere's disease caused this. I have T in both ears.
Anyway, I have noticed that when I do any exercise where I'm changing position quite dramatically such as gardening then I go deaf and of course the T becomes louder, until my hearing returns to normal.
This definitely feels like a blood pressure related thing. I don't have it when I stand up from sittting, only when I stand up from sitting whilst being exerted such as when I'm digging then squatting down to plants things.

anyone else have this?

While CSF leak is generally accompanied by an orthostatic (upright only) headache, this association is not universal and in fact, hearing loss may be more common than headache (Oncel et al, 1992). Orthostatic tinnitus is also possible.(Arai, Takada et al. 2003). The hearing loss of CSF leak likely results from lowering of CSF pressure, which lowers perilymphatic (inner ear) pressure, and results in a picture similar to Meniere's disease. (Walsted et al., 1991).
