It sounds to me as though you are being very resistant to any suggestions that have been made, so what do you expect us to tell you if everything we suggest is going to be shot down without a doubt?
Ground work always always always helps. A horse never stops needing any sort of ground work. Working on the ground is an excellent way of getting to know the horse better and vice versa. It will also give her a chance to possibly settle down and get more familiar with her surroundings without all of the extra stress of having a rider on her back.
Finally, when a horse throws its head up and is carrying its neck a stiff fashion, this does result in at least some degree of a hollow back. It's simply the way their muscles and anatomy works.
