I'm 22 years old, 5'8'', and 182lbs. I have a problem with a mole on the very top of my butt line. It's like pencil earaser size width and length, brown and almost feels like a bubble. When I press on it, it doesn't hurt. Some times it bleeds and itches. I've have it since I was little but it was never like how describe it, it was flat. Ever since I got pregnant in 2010 it grew. Then when I had my baby it grew a little more and felt like a bubble. I did make a appointment to see me doctor in two weeks but it's really bugging me what it could be. Any clue what it might be? Thank you. My name is Stephanie by the way.
