Question about swelling care and products to bring for travel after a petit procedure

Hello, my name is Mook 😊 I'm planning to go to Korea next week for a small petit procedure, but I'm worried about traveling home afterward because I have a 3-4 hour flight.

I'd like to ask those with experience: Has anyone traveled long distances after a procedure like this? How did you manage swelling and inflammation? Should I prepare any products from Korea, or is it better to bring things from Thailand? For example, ice packs, or specific creams or serums that help reduce swelling – which would be better?

Also, does anyone know if it's safe to fly in the first few days after the procedure, or how many days I should wait? I'm really unsure 😅 I'd appreciate any advice from those with experience. Thank you.
