Has anyone had any vertigo from their AN or is it more an issue of balance?
Depends on your definitions. Many have reported one or the other or both and many, unfortunately, equate one with the other."Vertigo is an abnormal sensation of motion. It can occur in the absence of motion or when a motion is sensed inaccurately. Spinning vertigo is usually of inner ear origin.
Disequilibrium is a sensation of impending fall or of the need to obtain external assistance for proper locomotion. It is sometimes described as a feeling of improper tilt of the floor, or as a sense of floating. This sensation can originate in the inner ear or other motion sensors, or in the central nervous system.
Positional vertigo is a sensation of spinning that occurs after the patient's head has moved to a new position with respect to gravity."

I had balance issues (disequilibrium) but not vertigo. I had difficulty walking in a straight line and felt like I was lurching from side to side like walking on a boat. That syndrome disappeared almost a year ago.
I never had dizziness or nausea or that room spinning feeling. In a stationary position (sitting, standing, driving) I had no balance issues at all.
