I have a lump behind my left ear what could it be?
it has just recently started to bother me the surrounding area hurts and in having these pulsing headaches come from the left side and I can't put no pressure on the left side because its uncomfortable. it's always been there but it's bothering me now. just curious if anyone ever felt this before . I am 21 and I can say I have had the bump all my life I'm just feeling pain from it now .
