What are these bumps on the back of my ears?

I had them all of my life. It’s two on each ear and they are symmetrical. I know a couple of other people who have them. What are these? What is the function? How did they get there?

I have them as well, and was once told by my massage therapist that they are calcium deposits.

You are both turning into rabbits.

It’s kind of sad, really.

Someone send them some lettuce.
