Meniere's Disease Research Program

[@marcuswhy]

I have delayed Meniere's Disease (Type 2). Diagnosed with SSHL 6.5 years ago and then 2 years ago, I got really bad vertigo attacks and have been getting them ever since. However, for some reasons I have Aural Fullness in both ears (for 6.5 years) even though I am deaf in one ear only and have tinnitus in the that same ear. I tried SERC for 6 months to know effect. Sibelium (flunarizine) for 6 months with no effect. I had 9 single shot Dexamethasone injections (10 mg). In the begininng I was getting 4 weeks to 4 months remission and in the past 3 injections, they don't seem to be working anymore. I am at a lost. I went to 3 ENT Doctors who said I have Meniere's Disease. I went to 3 Neurologists, 2 of which said I have Meniere's and one said it was Vestibular Migrane. Would you have any advice as to what I can do next?
