I'm a 17 year old female, and I just recently discovered a dark stain on the lower-left side of my areola (the dark part around the nipple). It looks like a birth mark, a bit darker than the actual areola, but I just discovered it recently...I have no idea if it was ever there before (don't recall seeing it).
Also, there's a tiny, and I mean real tiny, "zit" on it. It's a small bump. I don't feel any lumps.
Should I be worried? Or could this be totally normal?
