Hi!
If you were my patient, I would advise you that you should request to see a neurologist. You might have benign postural vertigo, or vestibulitis or Meniere's disease, or any of a number of other conditions that can cause dizziness/vertigo. There are medications that can help with the symptoms.
Ask for a consultation with a neurology specialist.
Good luck!
