A potential solution for my dizziness, or at least an answer

I was complaining on Facebook about falling again, and my stepmother mentioned that she also has trouble with dizziness and falling because she has Ménière's Disease.  According to the National Institutes of Health: 

Ménière’s disease is a disorder of the inner ear that causes severe dizziness (vertigo), ringing in the ears (tinnitus), hearing loss, and a feeling of fullness or congestion in the ear. Ménière’s disease usually affects only one ear.

Attacks of dizziness may come on suddenly or after a short period of tinnitus or muffled hearing. Some people will have single attacks of dizziness separated by long periods of time. Others may experience many attacks closer together over a number of days. Some people with Ménière’s disease have vertigo so extreme that they lose their balance and fall. These episodes are called “drop attacks.”

Ménière’s disease can develop at any age, but it is more likely to happen to adults between 40 and 60 years of age. The National Institute on Deafness and Other Communication Disorders (NIDCD) estimates that approximately 615,000 individuals in the United States are currently diagnosed with Ménière’s disease and that 45,500 cases are newly diagnosed each year.

I have a lot of fullness and fluid in my ears, particularly whichever one I slept on the night before. It itches and I can feel it sloshing about, and it's driving me crazy. I've been obsessively digging at them, and I'm thinking that's part of the problem, as I may be compacting things worse.  I had thought it was ear wax; now I think it's fluid plus a bit of skin from the ear canal that I'm digging at, as the fluid is mostly in the inner ear. I did a quick lookup and it fits. No tinnitus really, but I have the other stuff, have had episodes of dizziness or vertigo that lasted over 20 minutes (one last night, one in the summer where I had to be sent home from work in a wheelchair with someone driving me home because I couldn't move without the risk of falling down). I also had my hearing tested a few years ago and have a mild impairment (but I thought that was just basically ageing). I'll ask my doctor about it and what I might be able to do about it. I'm already on a diuretic, but maybe some of the other treatments and salt reduction could help.

I thanked her for the information; I hadn't heard of it (most of the subject expertise I have as a librarian concerns orthopaedics and paediatrics). I'll definitely take this up with my doctor. And if it isn't that, it may be something similar.
