Whats it call when you go and get scar out of the blue?
Your skin could be developing keloids. Perhaps you bumped a place on your skin and it is now developing a blemish, even if it was not a desperate lesion. When I get them I use tea tree grease (you can get it at a pharmacy, Wal Mart, herbal shops, etc) on it. Apply it twice a time and it should help keloids and scar fade.
It means that you should procure away from the blue!
Possibly amnesia, I'm sorry, I don't know, but I do know what you're talking just about. I have a mark on my right hand that I know wasn't other there, I freshly don't know where it come from. Sorry.
