I had chicken pox 3weeks ago.just three or four days ago, i started to feel itchiness all over my body, more on my back, neck and hands.what is this?

Hard to say: I cannot associate the prior history of chickenpox with the new itchiness. The skin surface should returning to normal.Sometimes excess scratching during the disease will open your skin to a variety of problems.Localized inflammation can appear or reactions to whatever you uses as a skin care product. If a persisting issue have it looked at.
