Why do race gain hit or miss itches and why does scratch help out?
Sometimes it can be to do with the nerves underneath your skin... but thats about as handy as i can be!
-Rachael H: Oh my god i get that ALL the time! It drives my boyfriend batty! I thought i was the one and only one lol.
Dunno, but have you notice that when you are trying to get to sleep at hours of darkness, you get one, later you get another and another. All within the mind, got to be.
i dont know why we go and get random itching, am sure someone can donate a scientific explaination.
I know that scratch does not help to seize rid of the itch, all it does is focus the brains attention elsewhere. As soon as you stop scratch the itch usually comes back!
the answer to explicitly quite simple its ur inert skin cells flakin past its sell-by date and scratching help ecause scratching is the course to cure an itch nothin else will do so good luck itchy
ably since I'm a Doctor u can come to me any time it is because the nerve surrounded by your body needs a itch.
I hear that it's a reaction below your skin such as something foreign is there and scratch it will usually relieve it because your body probably thinks the "foreign substance" be removed. Just like if you be being tickled by someone and you... draw from tickled and you try to tickle yourself and it just doesn't work.
