I've had a lump on the side of my leg for some time now, I went to see the doctor about it, and was told its just a skin growth thing, no harm. A while ago it started to smell, and so recently, I belive last week, I squeezed it and a brown cheese-like texture shot out, and it smells...What could this be? Im 19, 154 lbs, and in great health and physical shape. No major medical problems either.
