When you need to see a doctor, you may encounter communication difficulties due to language. You may also spend considerable time waiting for medical treatment in general hospitals and university hospitals. If you are not familiar with Korean, it is best way to go with one of your Korean friends for interpretation. It would be wise to go to a known hospital where language barriers are reduced. In an emergency, take some cash with you because some hospitals accept only certain credit cards. Medical insurance card is not recognized as a form of prepayment.
