Eczema Treatment Care

I have chronic eczema, and I have found nothing that really helps it, at least not long term. It is an extremely dry, extremely itchy red rash, and no matter what my doctor’s try, nothing seems to last. I use Vaseline Petroleum Jelly as a moisturizer. I use prescription strength Lidex cream. I use Prednisone when it gets too bad, and I haven’t found anything to use which is helpful for the itch. Any suggestions would be welcome.
