Totally agree with @turnitaround .
I was diagnosed with Menieres back in 1996, 6 months after a bad bout of labyrthitis which my specialist said had triggered Menieres. However, when my hearing didn’t get progressively worse or symptoms favour one ear, the diagnoses was changed to Endolymphatic Hydrops. I was discharged and told that the Hydrops would either fade “like a bad dream” which was highly likely as I was young or that I’d have some residual sympoms that my body couldn’t quite compensate for. It did settle down and I was okay mostly for over a decade, just some tinnitus and feeling of ear fullness, a bit dizzy when I’d overdone things, the odd sofa day needed but just got on with life . If you had asked me then I would say yes, it had burnt out.
Then several years ago I developed chronic migraine headache, worked on treatment for that and was totally fine for 6 months before MAV started creeping in and then went ballistic almost 3 years back. I probably have had MAV all along. I do have some “left side deficts” in tests so there could be ear damage too.
I thought Menieres was progressive and the vertigo episodic whereas MAV could be more 24/7. On that basis I’d say that Menieres doesn’t fade away. I know that Migraine/MAV can fade or morph given my own history. Lots of people on this site do get better and stop posting, some come back and post in Success Stories. Have a look there.Turnaround is a success story but thankfully maintains the site and keeps posting, giving lots of people hope.
Are you on a medication for the MAV? When I had chronic migraine headache the doctors only ever talked of “managing it” but with MAV there is talk of “curing” it. The MAV doc I see reckons if you are young and it’s caught quickly then diet, lifestyle adaptations and perhaps 1 med such as Nori for 6 -12 months should sort it. Because I’ve been untreated for decades, letting my brain get irritated then it’ll be a longer road for me and at least a few years of the right meds at the right dosages to quell it. For me, at best I’d say it only ever lies dormant. perhaps your body has compensated and perhaps you have made lifestyle adaptations that keeps your trigger threshold low.
