Before my surgeries, I remember the sensorial distress I would experience every time I set foot in a building with wide-open space in it—my hearing and vision were skewed or altered. I used to complain about it all the time. It was the worst a few weeks before my first surgery (for the shunt). I remember walking through a Walmart with my head feeling like a helium-filled, lead balloon, trailing above and behind me. I remember thinking that I couldn't go on and that if I didn't receive treatment I was done for.
Since my treatment about six years ago that feeling I used to get in enclosed, wide-open spaces is gone and has never returned, even though my left-side hearing has been lost.
That's an unusual detail about AN tumors. I've found that, in terms of sensorial distess, we seem to fare better with no hearing in one ear than with impaired or distorted hearing in one ear.
