When I read this article, I confused why I feel itchy. I always scratch when I feel itchy. If I can not endure I usually use balm to relieve. Perhaps I take the medicine to inhibit itch.
ReplyDeleteWhen I'm itchy, I couldn't control myself to stop scratch. After all when I forgot about itch, I forgot scratch too.
