Lymph node: Is this is a new round lump? If so, most likely a postauricular (behind the ear) lymph node which usually enlarges during a local infection of the ear canal, pinna, or scalp. The mastoid process is a normal protuberance of the temporal bone (ear bone) behind the ear, but this should be symmetric behind both of your ears.
