Walk-in clinic in Seoul, no appointment needed
Sick on a work trip, or something that cannot wait until next week? Walk in during opening hours and see a doctor in English the same day.
3F, 162 Apgujeong-ro, Gangnam-gu
Apgujeong Station (Line 3), Exit 5 · 1 min walk
VEI Clinic is an English-speaking walk-in clinic in Seoul, one minute from Apgujeong Station Exit 5 in Gangnam. Adults can come in without an appointment for most non-emergency problems and see Dr. HyunSung Park, a board-certified internal medicine specialist. Messaging us on WhatsApp first helps us tell you the likely wait.
How our walk-in clinic in Seoul works
Booking a doctor in a new country can feel harder than being ill. At VEI Clinic you do not need an appointment, a Korean phone number or a referral. Come to the 3rd floor of Beneheim City, the Jamba Juice building at 162 Apgujeong-ro, tell reception what is wrong, and you will be seen by Dr. HyunSung Park, our board-certified internal medicine specialist, in English.
Walk-in patients are seen in order alongside booked visits, so the wait varies through the day. If your time is tight, send a quick WhatsApp message with your symptoms before you set off. We can tell you roughly how busy we are and whether the test or vaccine you are hoping for is available that day.
Because Dr. Park has practiced in Korea since 2010 and trained in the United States, he is used to explaining the Korean system to newcomers: which pharmacy to use, how prescriptions work here and what to do if you need a hospital.
What you can walk in for
The walk-in service is meant for problems that need a doctor soon but are not emergencies. Typical reasons adults come in include:
- Cold, flu, sore throat, cough or fever
- Stomach upset, food poisoning, reflux flares or abdominal pain
- Burning or frequent urination that may be a urinary tract infection
- New rash, hives, suspected shingles or an allergy flare
- Headache, dizziness or feeling run down while traveling
- Running out of a regular medicine, or needing a sick note
- A flu shot or a hepatitis B vaccine dose
What happens at a walk-in visit
First, reception takes your details and a short description of the problem. A passport or Alien Registration Card is helpful, along with a list of any medicines you take. Then Dr. Park takes a history, examines you and explains what he thinks is happening.
If a test would change your treatment, he will suggest it and tell you the cost before it is done. Depending on the problem, that may be a blood test, a urine test, rapid testing where appropriate, or an ultrasound. Results that come back later are explained to you in English.
You leave with a plan in plain language, a prescription to fill at a nearby pharmacy if needed, and clear instructions on when to come back. If you need a sick note, or an itemized English receipt for your insurer, ask at the end of the visit.
A few things make a walk-in visit quicker: photos of any test results from another clinic, the date your symptoms started, and your travel plans if you are leaving Korea soon, so the doctor can fit treatment and follow-up around your schedule.
When a walk-in clinic is the wrong place
A clinic like ours cannot replace an emergency room. We do not have the equipment or staff for emergencies, and coming to us first can delay the care you need. If any of the following apply, call 119, Korea's emergency number, or go straight to a hospital emergency department.
- Chest pain or pressure, or severe shortness of breath
- Fainting, seizures, sudden confusion or a severe headache with a stiff neck
- Face drooping, arm weakness or slurred speech
- Vomiting blood, black or bloody stool, or heavy bleeding
- Swelling of the lips, tongue or throat after a sting, food or medicine
- Severe injury, a suspected broken bone or a deep wound
Who our walk-in service suits
It suits adult expats, students, tourists and business travelers who want a fast, English-speaking assessment from a specialist rather than a general screen. It is also handy for Seoul residents who work nearby and want to be seen over a lunch hour or after work on Tuesday, when we stay open until 20:00.
Our doctor is an internal medicine specialist, so we focus on adults. If you are thinking of bringing a child, please message us first and we will advise whether we can help or where you should go instead.
On cost: if you are enrolled in Korea's National Health Insurance, consultations are usually covered with a co-payment. Visitors pay the clinic fee directly, and we tell you the price of any test or treatment before it happens.
