Short answer

Colorectal and Anal Surgery(항문외과) is generally the first department to see for anal discomfort severe enough to make sitting difficult, as it specializes in conditions affecting the anus and lower rectum. If a colorectal and anal surgery clinic is not immediately available, General Surgery(외과) can also evaluate the condition initially. Depending on findings, you may be referred to other specialists.

Which department

1Colorectal and Anal Surgery (항문외과)
This specialty focuses specifically on the anus, rectum, and surrounding structures, making it the most directly relevant department for anal discomfort. Physicians here are experienced in evaluating a wide range of conditions that cause pain or pressure in the anal region. — First / second line: In Korea, a local 항문외과 clinic (의원) is generally the most appropriate first stop and does not typically require a referral letter. If the clinic determines further imaging or a hospital-level procedure is needed, they will issue a referral to a secondary or tertiary hospital.
2General Surgery (외과)
General Surgery covers the gastrointestinal tract including the lower bowel and anal area, and many general surgery clinics handle anal complaints when a dedicated 항문외과 is not nearby. A general surgeon can perform an initial evaluation and, if needed, refer you onward. — First / second line: A local 외과 의원 is a suitable first-contact option. If your symptoms point to a more complex condition, the doctor will guide you toward a specialist or hospital with a dedicated colorectal unit.
3Internal Medicine / Gastroenterology (내과 / 소화기내과)
When anal or rectal discomfort is accompanied by changes in bowel habits, abdominal pain, or suspected inflammatory bowel disease, a gastroenterologist may be involved to evaluate the colon and digestive tract more broadly. This department typically handles conditions from a medical (non-surgical) perspective. — First / second line: Gastroenterology is usually a secondary referral rather than a first visit for isolated anal discomfort. However, if you have co-existing digestive symptoms, starting here or being referred here alongside 항문외과 is not uncommon.

Go to the ER / call 119 if

If any of the following applies, do not choose a department — go to an emergency room or call 119 (Korea's emergency number).

Heavy or continuous rectal bleeding that does not stop on its own.
Sudden, extremely severe anal or pelvic pain accompanied by fever or chills.
A visible or palpable mass around the anus that is rapidly increasing in size or turning dark/necrotic in color.
Loss of bowel or bladder control appearing suddenly alongside anal pain.
Anal discomfort combined with signs of shock such as rapid heart rate, dizziness, or fainting — go to the emergency room or call 119 immediately rather than choosing a department.

Before your visit

Note the exact onset date and whether the discomfort started suddenly or gradually worsened over time.
Observe and be ready to describe the nature of the discomfort — such as sharp pain, pressure, burning, or itching — and whether it changes with sitting, standing, or bowel movements.
Check whether there is any visible swelling, discharge, or bleeding around the anal area, and note the color and amount.
Recall any recent changes in bowel habits, diet, or physical activity that may be relevant.
Prepare a list of any medications, supplements, or topical products you are currently using, including anything applied to the anal area.
Bring any previous examination results, imaging records, or medical history related to digestive or colorectal issues if you have them.

General principles

Anal discomfort severe enough to interfere with sitting is a symptom that can have several different underlying causes, which is why 항문외과 or 외과 is generally consulted first — physicians in these departments are trained to distinguish between conditions affecting the anal canal, perianal skin, and surrounding tissue through clinical examination. The severity of the discomfort itself does not determine the diagnosis; a proper evaluation by a doctor is necessary to identify the cause.

In the Korean healthcare system, it is generally possible to visit a local specialty clinic (의원) directly without a prior referral for this type of symptom. If the clinic-level evaluation suggests that more advanced imaging, procedures, or inpatient care is needed, the physician will provide a referral letter (요양급여의뢰서) to a larger hospital; note that while secondary hospitals (병원/종합병원) can be visited directly with normal insurance coverage, a referral letter is legally required for insurance coverage at tertiary hospitals (상급종합병원).

During an initial visit, the doctor will generally take a detailed symptom history and perform a physical examination of the area; additional steps, if any, are decided by the physician based on findings. General principles of evaluation in this specialty may involve visual inspection and, in some cases, instruments to view the lower anal canal — the specific approach is always determined by the attending physician and is not something to decide in advance.

Because the anal region is sensitive and symptoms can feel similar across different conditions, self-assessment alone is not a reliable guide. Consulting a medical professional early, even when symptoms seem mild, allows for an accurate picture and appropriate follow-up if needed.

FAQ

Should I go to a local clinic (의원) or a larger hospital for this kind of anal discomfort?

In general, starting at a local 항문외과 or 외과 의원 is the standard first step in Korea and is sufficient for most initial evaluations. A larger hospital is typically recommended if the clinic physician finds that more specialized equipment or procedures are needed, and they will usually provide a referral letter to facilitate this transition.

Could this discomfort be a sign of a digestive problem rather than a purely anal one, and should I see a gastroenterologist instead?

Anal and lower digestive symptoms can sometimes overlap, but 항문외과 or 외과 is generally the starting point because they can assess the anal and rectal area directly. If the examination suggests that the issue originates higher up in the digestive tract, the doctor will recommend or refer you to a gastroenterologist (소화기내과) as part of the overall evaluation.

What kinds of examinations are generally done for this type of complaint in Korea?

The specific examinations are always decided by the physician based on your individual history and findings, so it is not appropriate to expect a fixed set of tests in advance. Generally speaking, an initial physical assessment of the area is the typical starting point, and any further steps — such as additional visualization of the anal canal — are determined by what the doctor observes and what you report during the consultation.

Is there a difference in how this symptom is approached for elderly patients or children?

The department — 항문외과 or 외과 — is generally the same regardless of age, but the physician will adjust the evaluation approach based on the patient's age, overall health, and ability to cooperate. For very young children, a pediatrician (소아청소과) may be involved first to determine whether referral to a specialist is appropriate, so consulting a pediatric clinic first is a reasonable option for young children.
