Will there be language barriers if I consult with someone in Seoul? Is English or Chinese sufficient?

Hi everyone, I'm Mengju from Taiwan. I'm seriously considering getting a short treatment in Seoul, but I'm a bit worried about the language barrier. My English is okay, and Chinese is no problem, but I don't speak any Korean at all 😅

I'd like to ask if anyone has had a consultation in Seoul? Are there usually translators in the clinics? Or is it generally possible to communicate in English? I'm a little worried that if the doctor's English isn't good enough, or if I don't understand some of the medical terminology, will it affect the consultation's effectiveness?

Also, would it be more reassuring to bring my own translation app or prepare any documents in advance? Can anyone share their personal experience? Thanks!
