I'm not a doctor. I've known several folks--including me--who have had equilibrium issues, either temporary or semi-permanent.
All of them (me too) needed to have the rocks in their heads re-set. "Epley Maneuver".
When the rocks settle down where they're supposed to be, the balance issue is G-O-N-E. And that can be nearly permanent, or recurring depending on head position; sudden sneezes, getting bumped in the elevator, etc. All of this is called Benign Paroxysmal Positional Vertigo (BPPV)
Your inner ear has Otoconia/canaliths. These are lil' crystals of calcium carbonate that are supposed to be captured in a "sac". The sac ruptures for whatever reason, and those crystals--rocks--get stirred-up. Then they get tangled in the hair cells of your ear, and the world goes upside-down for awhile. Getting them settled down again requires a SIMPLE procedure, which most folks can do themselves after a few visits to have it done professionally. And if this isn't your issue...there's no harm done by the procedure. You might not have relief, but it wouldn't make things worse.
There's two variations of the procedure--one for left ear, one for right. The professional knows which one you need depending on whether your eyes spin clockwise or counterclockwise when you're actually dizzy.

The goal of the canalith repositioning procedure (CRP) is to is to move the displaced canaliths to treat a disorder called BPPV.
