Vertigo/dizziness and ear pathology

My mom has been suffering a pretty long time with dizziness, nausea and vertigo. She saw a specialist in ear pathology which explained it was a problem of the most internal region of the ear, gave her Betaserc and said there was nothing else to do.

It really affects her quality of life.

If anyone has any advice it would be greatly appreciated.

I had a bout with this recently. It came on from mercury toxicity I believe. I ran a bunch of RIFE scripts and got hit with it. May be a different root cause, but some sort of chelating or least testing may be worth while. I would hold off as it's a chronic thing and I'm sure more experienced members will weigh in. Hg testing is expensive I believe.

If it has to do with infection, some oregano oil on a q-tip works well directly, but may burn.

Other than that I might look into lymph system congestion.

Thank you so much for your input.
I don't think there is an infection, it's been chronic.

Any more advice is always welcome.
