Probable Meniere's Disease. It's the bullshit catchall diagnosis for "you have too much fluid in your ears and we have no idea why". The normal starter treatment is to reduce fluid retention (low salt and diuretics) coupled with avoiding vascular constrictors (alcohol, caffeine, niccotine, clown world). Salt reduction is going to be main challege since I know my consumption is excessive, and the others are easy to limit (aside from clown world, but c'est la vie).

Excessive fluid retention in my ears is causing problems. My salt intake is excessive, so that's an easy target to try first.
