Pretty sure it's nothing. Don't even worry about it. I only mention it because, while filling out the new patient form for my dermatologist office visit tomorrow morning, the following conversation took place:
Me: Why do they need an emergency contact?
Jon: It's in case they go to surgically remove it, and it ends up being an artery.
My mom: Or an alien.
Me: An ALIEN! IT'S NOT THAT BAD!!
Jon: It's pretty bad. Well...it's worse from the side.
