What causes an itch?
Thinking about the fact that out skin is comprised of millions of skin cells that are forever flaking off and then being replace, what is the real cause of an itch? I'm not talking about itches with other reasons, fungus, dandruff, etc. I mean just a regular itch. I have no idea about this one. Help anyone?
