Moon. I was thinking your jaw op was quite extensive and may have interfered with your eustachian tubes which keep the pressure equalised in your ears. Just a quick Google here:

"Symptoms of Eustachian tube dysfunction
If you have Eustachian tube dysfunction:

Your ears may feel plugged or full.
Sounds may seem muffled.
You may feel a popping or clicking sensation (children may say their ear “tickles”).
You may have pain in one or both ears.
You may hear ringing in your ears (called tinnitus).
You may sometimes have trouble keeping your balance."

Worth discussing with your doctor, if only to eliminate it.  As you know I'm deaf and if I've got a cold and stuffed up, I tend to lean when I get up sometimes and even have fallen off my bike as well a couple of times.

Damn, I hit several of those, I'll have to check with my doc to see what he thinks. I've had ringing, the feeling of liquid rolling around in my ears... Just one more damn thing I guess. I am making plans to get my health back as soon as I can start getting out and walking. Last time I went fish collecting I got stuck in mud and took me well over an hour to crawl 50'. That has inspired me to give getting my health back a priority... 

At least you've got an avenue to explore. Hope you get sorted mate.
