I had eczema when I was in my early 20's. There was asample cream that my doctor gave to me thatworked very well. Unfortunately, I don't remember what it was called but I know it had a high concentration of "urea" in it. You may want to ask your doctor.
Also, in the winter months, it's important NOT to use hot or too warm of water as it dries the skin even thoughit feels soothing. Drink lots of water, that helps.
If it gets really bad, use a cortisone cream available over thecounter such as Cortaid (sp) use sparingly.
Hopefully you'll outgrow it somewhat as you age (I don't know how hold you are though.)
