I have a mole on the left side of my neck. Well it has grown a very small different type of mole on top of it and its got me concerned. Not only that but it feels as if under the mole, it feels as if it is swelling or forming a knot. Now its not really painful at all unless it gets touch or rubbed. Should I be too concerned about this?
