Physical Therapy helped tremendously with my balance. I couldn't pass a road-side sobriety test stone sober! "Vestibular" balance is off when I can't walk toe-to-heal, loose balance when walking & turning my head like looking for something in the grocery isle or looking around the neighborhood while out for a walk. "Dizziness" when standing up from sitting/laying or feeling like the room is spinning is a whole different issue. Try to pin down which is your issue and talk with your Dr; "Orthostatic heart rate and blood pressure" readings look at changes from laying down, sitting up and then standing requires a different approach than physical therapy.
