I have a hard nonmovable lump behind my ear . What I mean by behind my ear is approximatley two inches from top of my ear, on my head, and about two inches above my lobe . From my limited understanding of anatomy , I believe the lump is located over my temperal bone. I noticed the lump a few weeks ago. My insurance will not be available for another 4-6 weeks, however. Does this issue require any immediate attention? Thank You
