Excessive scratching help!?

I was born with eczema and it has always been present on my life however for the past few years it jas gotten to the point where I will scratch and itch constantly. I can't sleep well because of it and I always have hives and painful scratch marks. I don't use scented anything and often take oatmeal baths. When I go to the dr it is always the same thing. A series of prednisone that clears it up for a week then it comes right back. Please help me. What can I do to stop being so uncomfortable? Is this really eczema or something else? I'm tired of the doctors throwing pills at me that only solve this temporarily. Ty for your time.
