Michele:
What you hae sounds like dyshidrotic eczema, a common and nonserious ailment of the palms and sometimes the soles. Cause is unknown, but stress can make it worse, and dirt and bacteria play no role. I would use over-the-counter Sarna lotion as needed for itch until you see the dermatologist. Meantime, don't bother changing anything, and don't worry.
Best.

Take care. The red patchs can get bigger on your hands and feet. I have just got it this year, must be a millenium thing. haha

my hands and feetsoles get a yellow color as well. I have been told it is from the skin cells growing to fast and this is what they look like. Be careful if they get to thick on the feet (use a pumice stone or something like that) because they can get so thick they crack and that is very painful to walk on.
