I also did have vertigo and still have dizziness, especially in my yoga classes. I suddenly went severely deaf in one ear and rely on my other ear that has hearing aid. It’s been hard because it cuts me out socially and cannot decipher the direction of sounds. I also got an episode of PMR years later but have now been recovered for the last 3 years. I’m wondering if it’s the norm for it to return? Do you still have PMR? I know there’s about 100 autoimmune diseases but haven’t heard of the inner ear disorder you commented about.
