I had a similar surgery 4 years ago and do not remember balance being a specific problem. I want to invite you to read in the top of our list Chronic Pain 101 for lots of good information. The post started on 9/15/2014 was written for and by people who have had neck surgeries, so you might find some helpful information. My own story is titled just like it is in my signature.
Best wishes to you in your balance and overall healing from your surgery!
