Cheryl, sorry its taken me a while to respond....the anger part is definitely part of the frustration cycle...as you know, eczema is like a burn and causes the scratching which then exacerbates the cycle........especially in Fire kids....
aloe seems to help calm the burning but I'm getting great results from coconut oil with probiotics added -
also there is something called Emily's skin soother
which works really well....
in terms of mood I would want more constitutional info...what's his passion, his fears etc....
but try giving him Bach flower remedy AGRIMONY which is about the water-fire-metal triad....
