I don’t know what is normal. Of course check with your doctor. I have had this happen after surgery in the past. In my case it was vertigo and two visits to a physical therapist that was trained in vertigo treatment got things back to normal. They thought it was being positioned in a different way for an hour or more that moved the crystals in the ear which can cause it. The other thing I had this time was dizziness standing up, but my blood pressure is now lower that usual.
Your primary care doctor or or post op surgical visit should help with this.
