I just noticed in the last few days a small lump behind my right ear in the crease area, my husband says it's a small lump, it feels like a small lump, it doesn't hurt or changing size or shape. It could have been there longer but I only just noticed it a few days ago, at first I thought it was a pimple but it doesn't hurt or anything, its not really hard, it feels a little soft and the size of a pimple.
