I'd like some advice on post-operative care after a petite procedure and what items I should pack for the trip.

Hi! My name is Aun. After deciding to have a small petite procedure in Korea, they said there would be some swelling. I'm traveling back overseas in a few days, and I'd like to ask if anyone who's had this done has any advice on managing the swelling? Also, what should I pack in my suitcase?

I'm actually not sure what products are best, or if I should look for specialized products or just general ones. What kind of things did others pack? And will the flight back cause more swelling? Any tips would be appreciated. Thank you in advance! 🙏
