I don't necessarily get the 'fibro itching,' but live in a very cold climate, and every year, my skin gets very, very dry. I find, like almost medfree, that oil helps more than lotions or creams. In fact, some lotions and creams can make things worse. I like to use olive oil, as it seems to provide a protective layer. Maybe your wife could try just a little bit at first, to see how it goes.
Chuck: How nice and thoughtful you are to help your wife! Have a great day.
