Debra, this is chronic disease by definition. The best I've found to cure ANY chronic disease, including but not limited to this commonest one I call The Itch, is professionally prescribed homeopathy. It takes training to manage chronic disease, it's rarely or never a "one remedy wonder."
I tell you how to hire a homeopathic vet on this page: https://vitalanimal.com/recommended-resources/ Scroll down to the AVH list and the video I've made to work your way through the list.
