swelling after electrlysis

Hi all
i have gone through 20 min of electrolysis treatment on my upperlip yesterday .she cleared a lot of hair yesterday without leaving any marks behind .I was quiet amazed .

But when i see today in the mirror i observed that my upper lip area looking bigger than before.

Is it due to loosing hair from there?
Is it due to swelling?Is it normal that you feel swelling like sensation after electrloysis?After how mnay days it will get reduced?

swelling is normal for lots of work in such a small area.

Swelling can go down in a matter of hours, or a week at most.
