Hey Everyone! So on my arm I have had a mole since childhood so it has been atleast 30 years. It hasn't changed. It is one color and under the size of a pencil eraser.I have actually never even worried about it. My shoulder started hurting a few days ago and ever since I just keep thinking this mole is melanoma and has spread to my shoulder. Ugh. Anyone have anything like it? Its just not a perfect circle so it worries me.
