After a minor procedure, how can I effectively reduce swelling and what should I get for home care?

Hello! I'm planning to get a minor procedure in Seoul soon and need to return in a few days. What are the best ways to reduce swelling and inflammation after the procedure during my trip? Is it possible to get good results even if I can't avoid the cold?

I understand that traveling with swelling is inevitable. However, I'm not sure what I should bring with me for the airport and the long flight. Are there any items that shouldn't be exposed to cold or moisture? If anyone has experience with this, could you offer some advice?

I'm eager to open the doors to cohabitation and my dreams. After I return, what kind of treatments would be good to consider near my home? I'm looking for good attitudes and experiences with simple participation!
