It sounds like you need a specialist to get to the bottom of this. If that isn't an option or it will be delayed, then I don't see anyway to not go the steroid route. The vets are pushing prednisone because they know it works very well.
Being so itchy has got to be very miserable for her. It's her quality of life in question. My vet doesn't like handing out steroids. But she does it anyway..because they work. They do carry risks like all drugs. Long-term use is more of a concern. But even for the pups that have to be on them life-long, isn't that better than them suffering? If they aren't getting relief, then how can they be happy?
