Just wanted to offer some sympathy as I suffer eczema too and know how distressing it can be.
I haven't had anywhere near the problems with eczema and hayfever that I usually do, and even my asthma has been non-existant during my pregnancy so I haven't really had to use anything.
When I do have a flare up, I try a warm bath with a sock full of oats under the tap. I also use goat's milk soap and no soap products, use the same washing liquid I always have that I know doesn't affect me - all the usual preventative things.
However, it sounds like you're looking for some relief. None of the non-prescription products I tried ever helped (and I tried a whole heap) and in fact some made the eczema worse (calendula cream was bad, for example!). Try to keep the area as moisturised as possible (with whatever cream suits you - I don't mind sorbolene or fragrance free cocoa butter, but both make DH itchy).
Oh, I just remembered. I take an inner health plus capsule each day, and flaxseed oil too. Since starting the flaxseed oil, my skin seems to be so much better (used to be really oily except for the dry eczema patches), but that was about 2 months before I fell pregnant, so it could be pregnancy, not the flaxseed oil!
Sorry for the loooong reply, but you might find something useful in all of this!
