I have this small bump on the righ side of my neck along my jaw bone. I was pretty sure it was just a zit at first, but it doesn't really look like one. It's hard, movable, close to the surface of my skin, and when I try to squeeze it like a zit, nothing happens. I have had it for about a week now and I am wondering if I should get it checked out. Also, there is no discoloration or moles there, so I'm pretty sure it's not melanoma.
