Did VRT for 3 weeks and it didn't help at all

I went to vestibular rehab for 3 weeks and my therapist said I should stop going because it’s not working and I have my appt. with Dr. Baloh next week at UCLA. She said if he feels I need to continue, I can go back after the appt. with him. Some stuff made me dizzy, but most of it was ok. It just didn’t change anything for me at all as far as the dizziness or headaches.
