The ENT referred me to the National Dizziness and Balance Center. I "passed" much of the testing, but they said they have still found that people with long covid respond well to the physical therapy. I have been doing the exercises for a week and a half, and I do think I'm seeing some relief. Many physical therapy places treat dizziness and balance issues and while the cause and expression from Covid may be different, maybe the same exercises are helpful. That is what I am hoping! Hoping to get back to work soon!
