Has there been any significant ear ache or discharge from ear as well?
I would suggest you take rest and avoid aviod positions precipitating dizziness
Try valsalva maneuver
to see if it helps.
Consider oral cyclizine
in case of vertigo
You would need to see a ENT physician to get an otoscopic examination of the ear to see if you have ear wax.
Because tinnitus and vertigo may also occur in cases of certain intracranial lesions so do see a physician if your symptoms are persistent.
