@needanswers7 I think you should call the 2 organizations, not just read the website. You could also ask for an ENT, (ear,nose,throat) specialist. This website may also help you.

I agree with @tinae about calling Mayo Clinic. At the bottom of this page, there is a ‘request appointment’ button to click on. This will take you to information. You might ask for appointment at Mayo Clinic Jacksonville since it is close.

I know it’s difficult, but you just have to search. Call university medical centers and large, teaching hospitals in your area, but wait until Tuesday.

I would try Johns Hopkins. They refer to it as Immune Mediated Inner Ear Disease. I've not been to their facilities but I've heard really good things about their rheumatology department through the autoimmune community.
