I don't know if this has anything to do with glands, but they are the first thing that popped in my head when I seen this...My niece has two lumps behind her ear. There is one right below the skull bone at the base of the neck and the other is right above this one. I was wondering what they were! They don't seem to hurt her. They feel like knots you would get if you bumped your head. Can anyone help me answer this???
