My daughter has a lump the size of a quarter behind her ear, it is somewhat soft, does not move from behind it, I have first noticed it tonight as she mentioned it hurting a little, and gave her a little headache earlier today. I felt around and it was a little tender for her.In checking it out, she also has a pea sized firmer lump about an inch below this and in her neck, it moves a little. She is six.
