3 or 4 weeks ago the inside of my right leg, just around the knee was very dry sking and itching and then a rash developed. the next week the left leg did exacty the same thing. the rash is worse, itches and burns especially when I am trying to rest at night. The rash is larger now. I have always, even as a child had very dry skin and very thin skin. I am diabetic, high BP and Cholestrol. Work full time as an admin, use to be anemic as a child and have periods of low iron. What is this rash? It is driving me crazy. And can getting the Shingles shot cause this? I got one about 4 weeks ago but the right leg had just started.
