It sounds like you have a very difficult issue on your hands. As many have alluded to already 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!
Best of luck!
