It's likely something called "benign positional vertigo." Sometimes called "top shelf disease" because it's often happens when you look up. Go on line. There are things you can do for it. One is called the "Epley maneuver." Very simple to do, and it works. There are YouTube videos on how to perform it and other similar procedures (like the Semont-Toupet maneuver). These are not quack remedies, but widely accepted by the medical community. Physicians sometims perform them right in the office.
