I'm not sure that this is a gland disorder, but this is what it sounds like to me.

I have a small lump behind on of my ears. I have had this before and it has gone away but this one is lasting much longer. When I rub it, I can feel it move, as if it was a small ball under my muscle. It feels a little bruised.

I would really like to know what this is. I assume that this is related to a disorder in the glands in my neck, am I right?

Thank you so much.
