Worried about the budget for medical procedures abroad 😅

Hello, my name is Som. I'm Thai and I'm thinking about going to Korea for something. But right now, I'm very confused about planning and budgeting. I don't know how much money I should prepare to be safe for everything, including plane tickets, accommodation in Seoul, and living expenses while I'm there.

What I'm most unsure about is: how many days do I need in total? The recovery period, the first follow-up appointment, and subsequent ones? Because if I stay too long, my budget will be exceeded, but if I've just returned and something goes wrong, I'd like to follow up. I want to know how people who have traveled there manage it.

Besides the initial consultation fee, are there any other costs that come up after returning home? I'm a planner and don't want to run out of money along the way 😅 Does anyone have experience? Do you have any tips for planning everything to be as cost-effective as possible?
