Hello,
My son had one behind his ear a while back and we just happened to have an appointment the next day with GI Doc, she said it was a swollen lymph node he had a zit close by so that is what she put it down to and it was gone within a couple of days. I think you can also get a swollen node there if you have a cold, sore throat or sinus.
I am sure you are driving yourself crazy like I did but it will probably be gone in a few days. Good Luck!
