It does sound as if she has some sort of neurological disorder. This is not uncommonly seen in dwarfs particulatly the hybrid dwarfs and the degree of spinning and problems the animal encounters vary. Some are very bad and cannot sleep properly or drink without the spinning however many live a long and fulfilling life with their disability.
It could be a stroke has caused the problem or quite possibly an ear infection. This would upset the delicate balance system in the inner ear.If she has just recently started it ,an ear infection is highly possible so you should see the vet for some Baytril. If she responds to this then you can assume that is what it was.
I hope she gets well soon
