I’ve suffered with Menieres for over 15 years. It is not genetic. It’s caused by a malfunction of the body’s immmunodeficiency system that attacks the inner ear. Symptoms include tinnitus, vertigo, nausea, loss of hearing, and can eventually result in deafness in some cases. A fellow sufferer eventually had his inner removed because of non stop vertigo. Treatments vary and results vary and it can remit but it never goes away. At its worst, in my case, unexpected violent onsets included vomiting, falling down, and horrible headaches. Really nasty stuff. Genetic? No. I’ve seen the best doctors and it confuses them all, like many immunodeficiency diseases. Bonus! I have another immunodeficiency disease: alopecia totalis! Docs can’t figure that one out either!
