Suggest Treatment For Severe Itching On The Body While Having Eczema

Hello. I have a history of eczema so i have had an itch at every part of my body at some point or another and I ve learned to deal with it, as it usually goes away in a few weeks time and the skin recovers back to normal. some spots where itches are reoccurring are the insides of my elbows. But over the last few months as the redness has cleared up, the skin in these spots has remained significantly whiter than the rest of my arm. It is pretty obvious if you look at my arm, I have these two white splotches on the insides of my elbows. Is this eczema or something else and how can I get rid of it?
