That's some very interesting information there, Slip-n-turn - thanks for posting.
If you can find a link detailing this manoevre that helps shift calcium deposits, I'd be very interested to see it.
Also, it's been said before, but for anyone who's been grappling with a suspected inner ear problem over time, I believe it's essential to visit a Maxillofacial Surgeon and rule out a TMJ issue. Bear in mind that ENT / Oto-neurologists aren't 100% equipped to diagnose TMJ - it can be subtle and non-obvious, and the only person who will be able to diagnose a slight misalignement will be a Max-Fac specialist.
One link I found referred to TMJ as the "great imposter" because its symptoms mimic that of so many conditions. General stress and jaw-clenching can also cause tinnitus and vestibular issues.
I also have identical symptoms to you, S+Turn. The Oto-specialists have said my hearing's good, and they are blaming stress... I'm open-minded about it being stress, but the clicking is not my imagination, nor the occasional sharp pains I get in the jaw joint when yawning. I'm off to see a Max-Fac guy - if he can rule it out, I can really focus on not being a stress-monger!
