I would only seek a qualified homeopathic vet for this, as this is chronic disease, nothing antibiotics and steroids and immune suppressive drugs can possibly cure. Please know that you can search out one to work with from my Recommended Resources page, and it can be long distance work, but it'll take repeated appointments and time and patience.
Please scroll down to the AVH list on that page and watch the video I've posted on how to choose properly. This is curable, but not DIY nor is it curable by allopathic meds. All the best to you on your journey to restored health.
