Lump under ear?

Kayla

This is a long shot but I’m curious. I found two lumps below my ear lobe on both sides last week but I don’t know how long they’ve been there. They’re maybe the size of a marble and hard and I can not move them. I’m just curious if anyone else has this? They’re not lymph nodes and I know this because I poked at one until a lymph node DID swell on top of it. My mom has it too but hers seems to be a bit more prominent on the right side? My doctor said they’re part of my anatomy and so did an ER RN. I’m just soooo curious to see if anyone else has this.
