Trying to figure out trip budget for a procedure in Korea—anyone else done this?

Hey! So I've been thinking about doing a procedure while I'm in Korea, but I'm honestly feeling a bit overwhelmed trying to plan the whole trip around it. I keep doing math on flights, accommodations, the procedure itself... and I'm not even sure what realistic numbers I should be working with. Like, how many days do people usually need there before and after? Does anyone have experience planning around recovery time?

I'm trying to be realistic about costs but also not get sticker shock when I land. I know prices vary so much depending on what you're doing and where you go, but I'm just trying to get a ballpark sense of what kind of budget I should be saving up. Should I be planning for like two weeks total? More? Less? And is it better to stay near a certain area, or does that not really matter?

Also curious—did anyone else feel nervous about the financial side of this before booking? I want to do it, but I also want to make sure I'm not being reckless about money. Any advice on how you pieced it all together would help so much!
