Welcome to HCM.
With little history it seems that you may be having either big black comedone or
Single lesion of molluscum contagiosum
Both the conditions are benign and harmless. And they might heal by themselves without treatment.
Black comedone is a form of acne
. And it may be extracted very easily.
Molluscum is viral infection, it may be cauterised under local anaesthesia.
However, you consult dermatologist
. Have firm diagnosis. And then go for treatment.
You will be alright.
I hope you got my answer.
