I have the same issues with balance, I can't stand on one foot without falling over, I can't walk a straight line with one foot in front of the other and closing my eyes it is a lot worse. I was also asked to walk on my heels and there was no way I could do that either.

I have the same issues with my ears, feeling full, feeling like fluid dripping, popping, and vibrating (electricity). I went to an ear nose and throat specialist and was told it is all coming from my neck.

The balance issues for me are caused by proprisemption (sorry I can't get that word tonight). Basically, balance is an issues of vision, sensors in your feet and I can't remember the third element. (not a good night for me).

I was cleaning the top of my microwave the other day and looking up makes me extremely nauseated and dizzy. I also have post traumatic vision syndrome and vision mid line shift syndrome. Both these contribute to unbalance, vision issues, nausea and dizziness.

Some people have had some success with vestibular therapy. I still do vestibular therapy but it makes me extremely sick, I don't know if I have had any significant improvement from the exercises. I also do vision therapy 3 times a week, the neuro optometrist says there is some improvement but it is very slight.

Good luck.
