I don't know about "behind the ear", but the body is full of lymph nodes. I had a lymph node on the back of my neck right at my hairline that became "calcified" as the doctor called it. It was about the size of a nickel and was not sore at all. I went ahead and had it removed though so that it wouldn't turn into anything serious later on-like cancer. Also, my surgeon said that if it was him, he would have it removed.

The best way to get medical advise is to see a doctor. There is no way to tell what a soft, painful lump on the heel of your foot without an examination.

Neither one will be pleasant. Consider something: Every tattoo that has ever been put on anyone in the 5000-year history of tattooing hurt, and every tattoo that has ever been done stopped hurting very soon after it was done. Would you rather have a tattoo behind your ear or one below your hairline on top of your neck? Then that's the one to get.
