This is such a minor thing but I just wanted to see if anyone else has had it or knows what it might be. A little black dot about 2mm across has appeared on my right first finger (on the fingerprint side). It looks like a pen mark but isn't and has been there for about three weeks without any change. It doesn't hurt, isn't raised and is quite regular in shape. Does anyone have any idea.what it might be and whether it will go away again? Thank you
