It sounds like you have a very difficult issue on your hands. There seems to be an abundance of methods to tackle eczema with some more fruitful than others.
You may have heard of a few natural methods which are starting to become increasingly popular of late, one of which was tried by a family member. We were all really pleased to see very favourable results over a long term and so it�s something I thought I would mention in the hope that you may find it beneficial.
After a lot of internet trawling I came across one site that appears to be a very safe source of reliable information as it provides a comparison and review of natural eczema treatments. I really hope this is somewhat useful!
