....not sure if this will help but your saying that hearing/noises etc. differs from day to day and mine is the same so hard to pin down cause. Reading about it all, it is very complicated sorting out hearing loss/tinnitus/hyperacusis/involving sometimes TMJ, sinus, what we eat/drink and what noises are around us.. I even read weather can play a part. I have moderate hearing loss and tried hearing aids for a few days couple years ago but didnt suit; also now have tinnitus but even that fluctuates. I feel mine could be hereditary but parents passed and I am 78 so cant ask... but also from many medications especially antibiotics but no proof and damage is done. The tinnitus is horrible but last year or so realized a lot of the noise I put down to tinnitus is hyperacusis (and having mri's with no ear protection over the years may have contributed, who knows?)...I can hear things much louder - so a mix of hearing loss yet can 'over-hear' shower on my head, machinery running/neighbours; even dropping something is overly loud compared to before yet can only hear half of what husband says! If there is a test for Menieres I havent had it and where I live there are only two ENT doctors and I cannot travel much due to fecal incontinence. So I just do what I can .. Ihave ipad and listen to relaxation tapes a lot and pick ones with vocals I can hear/tolerate... and when have mri ask for double hearing protection; so I hope you can find ways to cope because depending on the cause, it's hard to find a "cure" ... and with other medical issues to deal with can accentuate symptoms.
