Not pregnancy related, health ?

Hey guys!

So last night I coughed really hard, and after I did, I noticed a small, hard lump behind my earlobe. It hurts when I move my head. It’s below where my lymph node would be, so I don’t think it’s that. When I push on it, it doesn’t move. My hubby thinks it’s a muscle that I pulled. Any thoughts?

Also, I will be calling my doctor tomorrow, but I REALLY don’t want to go to the ER today if I don’t have to.
