I have this small bump on my skin. Its not itchy at all, and my parents said that they have had it too. Im not sure what it is, but at first it didnt hurt, and now it hurts alot when you touch it. Its not red at all and it pussess pink liquid.

My parents said that a seed will come out of it, and if it doesnt than another one will come when this one disapears . I want to know the name of this bump. Please help and thank you in advance !!
