I recently noticed that when I put my chin
to my chest, I could feel a lump
or something on the left side of under
my jawbone. I felt around, and I can't really feel anything when my head is upright. But when I tilt my head forwards and poke my fingers underneath my jawbone I can feel a small lump that I can "move" to the chin side of my jawbone quite easily.
I felt on the right side and I have the same there, and I can move that one too.
