I’ve taken a diuretic briefly (a thiazide) I maybe should have persevered but didn’t have earth shattering effect. Change of tinnitus was about the worst effect. I believe @GetBetter may be trying one too.
As you may know I have had a diagnosis of MAV but more recently a diagnosis of perilymph fistula with secondary hydrops. Fistula are hard to diagnose but it was much more clear in a case like mine as I had definite trauma to the affected ear and a sensation of fluid in my ear every morning.
Unless you have episodic attacks with hearing impairment and develop low frequency hearing loss it’s unlikely to be menieres. More likely you have secondary hydrops (SEH). I’ve not been able to find anything truly illuminating on the natural history of secondary hydrops it’s all a bit vague but some say it clears up after the driver is resolved, in my case if my fistula heals (in progress I hope!). Not tried your particular diuretic.
Be grateful they’ve found an issue instead of just bucketing you in MAV with no explanation.
My theory is SEH is a lot more common and in fact MAV = SEH. I also have a suspicion that most tinnitus must be caused by inner ear hydrops. There is scientific evidence that MAVers with tinnitus have Hydrops.
I’d carry on with the Ami if it’s helping. Indeed the fistula flow chart on Hains site recommends a holding pattern of MAV meds.
Be very interested to hear how you get on with the diuretic.
