Rita:
Hives aren't flaky, whereas eczema is. Eczema can be aggratvated by stress, but cold and dry weather is even more likely to bring it on. Try applying over-th-counter 1% htdrocortisone
twiceTwice-a-day a day. Ifr that doesn't help, perhaps a doctor can prescribe a stronger cortisone cream, which should do the trick promptly (though of course it may recur from time to time.)
Best.
