If it's a localised recurring patch, is it a food or environmental rx?

What is your experience? DS2 has this patch of eczema around one of his ankle that is always the first to flare up, and the last to heal. After two months and much work, we are finally seeing beautiful skin from head to toe again after our last diet infringement at the zoo (urgh), EXCEPT for that patch. Everytime I think it's finally going to clear, he has a middle of the night scratching again. 

If it's food should it not be a more generalised itching through the body? He has been tested very allergic to dustmites, and that was the thing the allergist told us to concentrate on. We do see a link between eating out and his scratching, but I would be really happy to be wrong!

My DD2's eczema was on her inner thighs (like diaper chafing except she was potty trained) and it was from corn. As soon as corn went out of her diet, the eczema went away. If there was a goof up, it came back. So she didn't have generalized eczema.

If you notice it after eating out, what do you guys eat out that you don't eat at home? Or what are you exposed to when eating out that you aren't exposed to at home?

My dd has an eczema patch on her chest that NEVER totally goes away. I call it her "signal patch" because I can tell if she's reacting, it flairs up. She has food intolerances. She only gets more generalized itchy/widespread eczema if she continues getting the offending food.

For J (18mos), that patch used to be under his belly button. It would be almost gone, then flare up again in relation to food. Once that spot completely healed, a couple months later he started getting eczema in other places, but not there again. When he eats a trigger food (or what we suspect are trigger foods), those are now the spots that flare up.

My theory is that if there is a spot that is "damaged" (a rash, friction, dampness, dry skin, whatever), that is the spot(s) that is/are going to show a food reaction first.
