My ds had a severe problem, and NAET has completely resolved it (Yeah!) In our case, the eczema was over 90% of his body - oozing and in burns -- ALL of it related to allergies both food and anvironmental.
I've done lots of research, and here are some ideas that worked and some comments:
1. try www.naet.com
to learn about treatment, find a practitioner and get a good book to read more - see case histories too
2. try a calendula/petroleum based cream to create a barrier - we also kept socks on hands, covered the itchy ares, etc. a cream called sudocreme which is sold in England works well too, if you have any friends in UK, or try to get over internet
3.steroids suppress the problem, and usually will re-appear as asthma
4.try an elimination diet ASAP - milk,soy,corn,bananas,strawberries,shellfish are big culprits - in our case we could only eat 6 things for about 6 months until the treatments kicked in
5.the cod liver oil is fabulous - my son takes 1 teaspoon daily with food - try orange flavored from health food store - helps strengthen the immune system - feel free to email me directly for any more info, support or questions!
