Masseter muscle reduction day 2 review

I had masseter muscle reduction yesterday. The swelling was no joke. I had it done at a place located in Shinnonhyeon Station. Even after receiving the second retouch, my face is swollen. Do I have to eat and drink for another month? ㅠㅠㅠㅠㅠㅠㅠㅠㅠ They say it's free, but I have a lot of facial muscles, so it looks like it's swollen a lot haaaa..... At home, they tell me not to do it again ㅠ I think I need to get a second retouch, but if it swells like this again, even at home will say something. ㅠㅠ I want to eat pork belly ㅠ
