My dear wife Lorraine has suffered this problem since she was 14, and she is now 54. I made her some ' Colloidal Silver ' and gave it to her in a small spray bottle, she has used it with very good effect. It stops her itching and sooths the eczema, it usually goes completely within a few days, a week maximum. Since she used it about 6 Months ago it has gradually improved, doesn't erupt so often and is tolerable now.
I don't of course know where you are in the World, but I will gladly make some for you if you live anywhere near me. I live in Nuneaton , Warks, England.
It appears that test done on ' Colloidal Silver 'that is sold in the shops is more or less useless.
If you live in the U.K I'll even post some to you free.
