Hello, My boyfriend has a very small hard movable ball under his skin on his chin. It is not noticeable when you look at his chin, you can only feel it. It doesn t hurt when he or I move it, however we want to know what it is and how to remove it. I have poked it with a needle but it does no good other than makes him bleed. At first we thought it was an ingrown hair but now we believe it is something else.
