I occasionaly get these bumps on my face that take a few weeks to surface and go away, which I'm fine with. But there's this one bump on my cheek I got a few months ago. It started out the same as the others, and I tried to pop it when it surfaced, but it seemed to have gone back under the skin. When I squeeze the area around it, it feels like there's a small ball under my skin. The skin around it is not red, it looks barely darker than my regular skin color, and it's been on my face for I believe 2-3 months.

Should I be more concerned?
