The diet thing is very convoluted and irritating. I remembered while typing my response to you how much I suspected my diet had to do with all three flare-ups, because the situation was the same each time, but I can't really do much about it now because I need this diet for other reasons.

That's why I had forgotten my discovery.
Maybe I ought to try this kind or some other appropriate kind of black soap for shampoo. The eczema black soap makes all the difference with my hands. It's been tried and true for years, and those flare-ups only come back when I'm stubborn enough to use other soaps. I can get away with it for a little while, depending on the soap, and then bam! eczema's back. I've used one bottle of another kind currently and an itchy bump appeared on my hand this morning.
This kind smells good, to me at least, but it can temporarily "stain" washcloths if you leave some of it in there without lathering it all up.
Sorry about the stress. I believe I've noticed that before too, the instant irritation.
