Hi Jo, I know you may read this a lot, but everyone is different. There are, though, similarities and knowing that there are others who share your experiences can be somewhat comforting.
I had dizziness for four years before my diagnosis. It was mild and manageable until two weeks before my surgery. Even though my balance was trying to compensate before surgery, the post surgery balance issues were much worse for me. I still struggle with walking a straight line, darkness, and large open places with high ceilings. For most of us who face microsurgery, the brain will suppress the function of the balance nerve on the good side when it senses that the balance nerve on the tumor side has been removed. The two sides normally work in tandem with each other. So after surgery, initially you rely on your visual perception and proprioceptors (pressure sensors like in the ankels, hips, feet, etc.) for your balance. The brain has to relearn to keep you balanced with the two remaining systems until it releases its hold on the balance nerve on the good side. This happens over time and with exercise. Balance recovery is definitely possible, but it does not happen over night. And again, everyone is different.
You may have read on the AN site where many report they have more problems when they are tired or have pushed themselves too hard. This seems to be a common thread. You will also read many, many success stories and tales of improvements. I will admit that I have had some rough times with balance since I returned to work. I hit the 5 months-out mark on Friday, the 13th, and observe that I have seen noticeable improvement in my balance in the past two weeks. I also have a lot more energy and am finally able to survive a 5 day work week. On days when the balance is off and the head has spasms, I just remind myself that "This, too, shall pass." And it will.
Keep us posted on how you are doing, and stay positive.
