Count me out. I will get better. So might you!
All MAV is is a symptom cluster. There could be a number of causes and many people may find symptoms resolve spontaneously over time.
I don't believe migraine is the cause (24/7 fluctuations in tinnitus, ear pressure, pain and dizziness is a migraine?! Yeah right and I'm Abraham Lincoln!). I'm sure for many the cause is physical and migraine is one of the outcomes.
As I'm sure you've noticed ENT technology is a bit limited. They have only just developed a test for the presence of perilymph fluid in the middle ear (but this is only in pilot in Japan at the moment). They dont know yet what is happening during a vertigo attack (I'll tell you: it's fluid leaking into the middle ear causing movement of fluid in the labyrinth and associated sensations). They dont know what causes 'fullness' ( I'll tell you: it's perilymph fluid getting stuck in your eustachian tube because it's blocked with 'gunk' probably dried blood)
I'm CERTAIN my 'MAV' is actually a fistula in combination with secondary hydrops and I've seen both huge improvements since day one (I'm currently on holiday) and exacerbations (like yesterday I got on my haunches to take a photo and immediately felt dizzier on standing back up (and remain so the morning after) - I'd just split it open again!). It all started with minor trauma to my ear. Yet I've been diagnosed with 'MAV'. Go figure.
Don't lose hope.
I have every belief that my condition will eventually heal but having a fistula heal is quite tricky due to the pressures involved, the complication of raised inner ear pressure and disturbance from day to day normal activity. It could easily take years.
And the reason why MAV may come back for some is that a fistula once present may represent an ongoing weakness that may breach again especially if ear pressure is elevated (as a result of the bodies reaction to the injury)
Here's a 'MAV' recovery story to give you hope (it's clear from described symptoms it's 'MAV' as chronic labyrinthitis does not exist):
PS I don't believe surgery for fistula makes sense because it's too easy for it to split open again so you are best to ride it out and let nature take its course
