32 year old married male here.
Non-smoking, social drinker.
I have a lump behind
my right ear in the postauricular area around
1 cm across, more flat than raised, and
most prounounced when I turn my head to the left. It's not painful, not moveable, and
when I hold my finger to it I can feel my pulse. I first noticed it around
11 months ago when I had a very itchy, red rash covering my ears, and
there has been no discernable change in size or shape since then.
