if your tinnitus is related to your vng test it should resolve in a few days to a week. as you may know tinnitus is common in many inner ear disorders like menieres. it could be just be a coincidence that you have tinnitus today but then again it could have some unknown association. people getting a vng certainly can having dizziness or even nausea/vomiting but tinnitus would not be a common test side-effect.
