What does chronic urticaria mean?

It is a medical term referring to a course where hives recur for more than 6 weeks. Chronic urticaria refers to cases where wheals or angioedema recur for more than 6 weeks. Even if they do not appear every day, please record the triggers on the days they occur, the duration, and the response to medication.

How is it different from similar conditions?

This does not mean that a single wheal stays in the same spot for 6 weeks. We distinguish between the duration of individual wheals and the overall period of recurrence.

Why is this important in skin care?

Unlike acute urticaria, the recurrence schedule, triggering stimuli, response to antihistamines, and the burden on daily life must be evaluated together during medical consultation.

What should be checked based on my symptoms?

If your lips, tongue, or throat swell, or if you experience shortness of breath or dizziness, seek emergency help immediately, regardless of the chronic course.

Condition GuidanceChronic UrticariaChronic urticaria is a condition where very itchy bumps or raised wheals recur daily or on most days for 6 weeks or longer. A single wheal usually disappears within 24 hours, but new ones may appear in other areas, and their shape and location may change. Depending on skin tone, they may appear pink or red, or they may be difficult to see if they are similar to the surrounding skin color. Angioedema, which is deep skin swelling, may accompany this in the eyelids, lips, hands, or feet. Swelling of the face, mouth, tongue, or throat, throat tightness, difficulty swallowing or breathing, dizziness, or a feeling of fainting may indicate anaphylaxis; seek emergency help immediately.Medical Evaluation GuidePrepare for your visit with skin photos, symptoms, and medications usedRather than a single photo, please prepare a chronological record of the date the symptoms first appeared, the timing of when they disappear and reappear, itching and pain, and the medications used and your reactions to them. It is helpful for the medical evaluation to take photos of the same area from the same distance during both normal states and when symptoms are most severe.Medical Evaluation GuideRecurring skin symptoms: When should you start Korean medicine treatment together?If the same area recurs even after necessary treatment, or if itching continues to interfere with your sleep, work, or school life, herbal medicine treatment can help manage the recurrence interval and the burden on your daily life. For infections, sudden worsening, or new skin changes of unclear origin, we will first connect you with the necessary tests before proceeding with the treatment sequence.
