I have a small, hard, painful, movable lump about an inch in front of my right ear. I first noticed it several months ago. It has not gotten any bigger but has possibly gotten a little more painful and tender (i.e. if I lean my head on my hand and accidentally press on it, it hurts a lot). Is this something I should be concerned about? I am also four months pregnant, but I definitely noticed the lump a few months before my pregnancy.
