Ive got a mole on my face and over the last few months its been, growing, and becoming inflammed every so often but recently its always inflammed and its had a hard lump under it, that carries in about almost 1cm below the mole under the skin, its a darker colour than my skin, it almost looks black, and is very noticeable, its been bleeding and pus also comes out. It's painful to the touch and is itchy.
