I have had this lump in my neck for about 2 years now, at first it was sorta like a pimp which had a an oil like substance in it. I squeezed that out but it didnt go away, instead the centre became fleshy. On the surface of my skin the mass has a scabby top. What could this be? I have notice that other lumps have formed around my neck and in my ear lobe but have a different feel and often disappear after a while.
