Your description is consistent with eczema, not fungus. Eczema comes and goes, is indeed "rashy," and fluctuates with no pattern. Environmental matters (food, soaps) rarely contribute in a meaningful way. I can
not make any sense of your post-Zithromax episode.
In my experience, Elidel doesn't work very well for extensive cases like yours. A key is to have a large enough supply of a topical steroid cream, so you can
put it on wherever you need it.
