is it normal to still be swollen after getting a mole shaved off?

I went in three days ago to remove a mole located above my upper lip and still have allot of swelling left. It is not bothering and doesn't look like it's getting infected just is swollen. they had to inject it like four times in order to numb it up would that make a difference? I called them but they haven't gotten back to me and it's the weekend. so seeking some answers on her. - thanks in advance
