I have this bump behind my ear, Behind my lobe (makes my ear lobe stick out). I thought it was a pimple at first but it doesn't have a head on it, I woke up this morning I didn't notice it, but at work around noon I felt it then looked in the mirror and saw this bump thing. I was a little sick for about a week I think it was a cold its going away now, I don't know if that has anything to do with it? Do you know what it might be? Should I go see a doctor about it? I have a picture of it

Hey Jay,
First of all... Yes, always see a Doc. About suspicious things on your body. If its nothing, your safe. Second, I had a bump or "bubble" behind my ear as a child as did my father. It was rather larger. It was very... "smooshy" (sorry if that's gross) BUT! It was just water! For myself and my father. So it was drained and all is well. But please don't take my experience as your answer. PLEASE go to the Doc. To be safe. Good luck!

Does the bump look like a bug bite or is it like a lymph node under your skin? And it just appeared today? Does it hurt?

Sorry, there can be many causes of this bump, you should probably give some more details.
