This may seem like a strange subject line, but I believe I have an insight that is worthy of sharing.
Many of us have experienced balance issues, dizziness, wonky head, waviness in our head etc.. post op when standing, walking, or running. For some of us, that experience is MUCH worse when we are outside, in the shopping mall or in other active places. That has been my experience also. The theory expressed to me was that the greater activity outside and in malls etc... was harder for our brains to process.
First a little background:
At the time of my surgery I wore mild reading glasses. About 4-5 months ago I thought I noticed that if I kept my reading glasses on while walking around the house the intensity of the balance related issues I was experiencing was diminished. It didn't seem like it was vision related. It felt more like the frames were blocking a small portion of my peripheral vision, helping me focus on what was in front of me, and that was helping my balance.
I needed a new pair of glasses and had some other issues related to surgery I wanted checked out so I went to the eye doctor. He checked me out, gave me a clean bill of health, a stronger pair of reading glasses and a mild lens for distance (bifocals). To my utter amazement, when I wore the glasses OUTSIDE for the first time, all my balance related symptoms were greatly diminished. That remains the case even now.
I have done some experiments with glasses on and glasses off and it seems clear that I am better with my glasses on. I have also tried to determine whether it is vision or peripheral vision that is the issue by walking around with my hands cupped at the side of my eyes like horse blinkers and I am better that way too. These are hardly scientific studies, but I felt compelled to share them because perhaps I can help someone.
If you don't wear glasses, try walking around with your hands cupped at the side of your eyes. If that helps, I would consider sun glasses or some other extremely mild decorative glasses when you go outside. It may help.
