Is my English sufficient for a consultation with a clinic in Seoul?

Hi, my name is May, and I'm planning to go to a clinic for C-section treatment. This is my first time in Seoul for aesthetic treatments, but I'm a little worried about the language barrier. I speak some English, but not fluently. Could anyone tell me if most clinics have staff who speak good English, or should I bring a translator with me?

Also, I'd like to know what kind of experiences people who've had consultations there had. Was it easy to find staff who spoke Thai? I'm worried that medical terminology might be difficult for me. Has anyone had similar experiences? I'd love some tips!
