just a quick reply to you. haven't read the other posts. but maybe this is something that could really help you - it has REALLY helped my dd!
we're doing acupuncture and herbs with a traditional chinese doctor. in conjunction, we are avoiding dairy as that seems to be a trigger. my dd has eczema but i believe the root cause is an overgrowth of yeast that she's had since the beginning. i've had it most of my life too.
it's only been a month and a half and i can see concrete progress. she no longer has allergy eyes. the itching is less often. and when we do "cheat", the reaction is less and less severe, and it takes longer to show up. all of this helps me feel immensely better, that we are on the right track.
i think it can be difficult to find a traditional chinese practisioner that will treat children. but it can be done! ours is very expensive as well, but when you've tried elimination diets, gluten-free/casein-free, every lotion out there, probiotics, etc..., all to little avail, the $$$ doesn't seem so bad.
good luck to you. i know the hell you're in and i hope you find a solution soon.
ps. acupuncture does not hurt at all. for children, they don't even leave the needles in - just a quick in and out to stimulate healing. the stuff WORKS. immediately after leaving the office, her eczema is about 50% reduced. and, she loves it. she asks to go back and have her "leg scratched". it's very relaxing. the herbs are bitter but they are already made up into a tincture for you- you just add some drops to juice. my dd has no problem with them.
