After reading another forum, some people on there had found this, I looked it up and did a little research, and it's dead on.
I haven't found a cure
by finding the name for this, but one thing that's helped me is immediately after showering, using my hair dryer on my legs. It takes approximately 8 to 10 minutes, but the itching subsides. It apparently has something to do with the moisture/water drying on your legs, air touching your legs, and the drying.
