Hi all just wondering if anyone has ever woke up one morning with a bump on your forehead right where your hairline is? It's weird I don't recall hitting anything but I have this bump on my head that the Dr's says will go away it's about the size of an eraser on a pencil, soft and it doesn't hur but it goes down a little then the next thing I know at the end of the day its visible again.

some people say to just leave it and it will go away... can anyone help or has anyone had this before? Jus worried it might be something more but I'm not paying attention to it even though at times it does get really visible.
