Hi! creamy, thank you and the same to you and family.
You were a diagnostic conundrum as an unfortunate "shake of the dice" dealt you one diagnostic inner ear problem in one ear and another different inner ear problem in the other.
The BPPV should burn itself out with no residual damage, but the Meniere's "may" be a little resistant leaving you with some deafness on that side. However, the injections are certainly the next move.
You follow up is satisfying to me and much appreciated.
