Nipple discharge: Is this normal?

So, about six months ago, this little red spot popped up on my face, and at first, I honestly just figured it was some annoying pimple, but it’s just sitting there refusing to budge, which is kind of frustrating. It landed right smack in the middle of my forehead, positioned perfectly between my eyebrows, making me look like a total parody of Julia Roberts. 🙂
Since both of my parents have dealt with issues regarding skin tags, I can't help but worry that this little blotch might be the start of something similar. Is there any way to actually get to the root of it now, or am I stuck just waiting for it to fully develop so they can eventually burn it off, freeze it, or whatever doctors do for skin tags? 😕

Why are you so sure it's a wart? Couldn't it just be an atheroma or something else entirely?
