Language barrier at Seoul consultations?

Hey everyone! So I'm planning my first trip to Seoul for a consultation and I'm honestly a bit nervous about the language thing. My Korean is like... non-existent lol. I know a lot of clinics have English-speaking staff, but I'm wondering how real that actually is? Has anyone here done a consultation with just English, or did you bring a translator or something? I'm trying to figure out if I should stress about this or if it's actually pretty manageable. Also curious if having a friend who speaks Korean would even be helpful, or if they usually prefer you to come alone anyway? Any tips from people who've actually been through this would be amazing. Thanks!
