What should I record before my medical evaluation?

Please prepare a map of the itchy areas, the time of day when symptoms are most severe, the relationship between itching and showers, heat, food, or medication, the number of times you woke up during the night, and a list of current medications and supplements.

Current discomfort

Chronic Pruritus: When was it most uncomfortable?

If your current discomfort is similar to the experiences below, we can determine during your medical evaluation whether it is chronic pruritus or another skin issue.

Those who have experienced whole-body itching for over 6 weeks, but initial rashes are not clearly visible
Those whose symptoms subside only on days they take antihistamines, but nighttime itching returns when they stop taking the medication
Those concerned about systemic causes such as new medications, weight changes, fatigue, or issues with the liver, kidneys, or thyroid

Discomfort that persists after tests and treatment

Does the same area become itchy again after you stop using ointments or medication?

The same area may become itchy and red again after a period of improvement while using medication. This does not mean that your previous treatment was ineffective. During your consultation, please tell us how much you improved, when it worsened again, and if the itching has affected your sleep or daily life.

We establish a treatment plan based on your skin condition and the pattern of recurrence. If there are causes that need to be addressed first, such as an infection or rapid worsening, those treatments take priority. Korean herbal medicine treatment considers remaining itching, heat sensations, and oozing, as well as sleep, digestion, and fatigue, to set primary goals and progress criteria; the sequence of necessary dermatological treatments is also adjusted based on your actual response. Lifestyle management is tailored to support treatment goals and minimize skin irritation.

Medical Evaluation GuideThings to check when itching prevents sleep at nightFirst, check if the swollen areas generally fade within a day, or if rough and cracked skin remains for several days. If the wheals have subsided but you continue to wake up, record both the changes in the wheals and the number of times you woke up. If rough skin and scratch marks remain, the cycle of dermatitis and the itch-scratch cycle must be examined together. Even if there are few skin changes, please seek medical evaluation if generalized itching is accompanied by jaundice, weight changes, or fever.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 GuideWhat does Korean medicine look for when skin conditions recur after dermatological treatment?Please list separately what has improved and what still remains after dermatological treatment. If redness, oozing, or wheals have decreased or infection is controlled, record which treatment led to the improvement. If dryness, cracking, itching in the same area, or waking up at night remains, specific goals for Korean medicine treatment can be set. If there is new pain, pus, or rapid spreading, do not consider this part of the remaining recovery; seek medical evaluation first and do not change your prescriptions arbitrarily.

Terms used in the chronic pruritus guide

PruritusPruritus refers to itching. This can include itching with distinct skin lesions as well as itching with few visible changes.RecurrenceA recurrence may be the same condition reappearing, but it could also be a new condition that looks similar. It is necessary to check if the location, appearance, and triggering situations are the same.Skin Disease Pattern IdentificationPattern identification (Byeonjeung) is not about giving a different name instead of a disease name. It is the process of determining which treatment to prioritize by observing concurrent changes, such as oozing, heat sensation, dryness, and lichenification, alongside sleep, digestion, and fatigue.

When herbal medicine treatment is the primary focus

Chronic Pruritus: If symptoms worsen again even after treatment

Even if there is little visible rash, itching can significantly disrupt sleep and concentration. Based on a necessary evaluation of systemic causes, herbal medicine treatment can be the primary focus to address nighttime worsening and the cycle of dryness and fatigue.

Before the consultation

We ask where it appeared and when it worsened again

We examine the itchy areas and timing, skin changes before scratching, dryness and lichenification, as well as systemic changes including sleep, bowel movements, urination, and current medications.

During treatment

We check if not only the itching, but also sleep and daily life are improving

We compare the frequency of waking up during the night, scratching wounds, the duration of itch-free time, and the recovery of daily activities.

Treatment sequence

We set the goals for herbal medicine treatment by identifying the problems that need to be resolved first

If there are causes that require immediate priority, such as infection or rapid worsening, those treatments come first. Subsequently, for herbal medicine treatment, we determine the primary goal of recovery by examining current discomfort, recurring patterns, sleep, digestion, and fatigue, and coordinate the sequence with necessary dermatological treatments.

While reducing aggravating factors through lifestyle management, herbal medicine treatment determines the initial target by analyzing the pattern of lesions, sleep, digestion, and fatigue through pattern identification (Byeonjeung). Necessary skin treatments are continued in accordance with the progress.

Points to check first

Chronic Pruritus: Symptoms and when to seek prompt medical evaluation

Chronic pruritus is a condition where itching lasts for 6 weeks or longer; rather than the initial rash, only lines, scabs, or color changes caused by scratching may be visible. Since causes can include not only skin issues like dryness, eczema, or scabies, but also new medications, liver, kidney, thyroid, diabetes, blood disorders, and neurological problems, we first organize the systemic distribution, medical history, and necessary tests. For itching that persists even after the cause is identified, we look into body heat, dryness, sleep, digestion, and fatigue. Byeonjeung (pattern identification).

Director Choi Yeon-seung's Clinical Perspective

Chronic Pruritus: How is the direction of Korean herbal medicine treatment determined?

Chronic pruritus is not grouped under the single word 'allergy.' After ruling out systemic causes, medications, infections, and skin diseases, if the itching persists, we perform a pattern identification to see if the skin is red and hot, dry and worse at night, or if it overlaps with digestive issues, fatigue, and poor recovery.

Changes to be confirmed in this treatmentWe aim to reduce the time spent itching, the number of scratch wounds, and the frequency of waking up at night to increase the time the skin feels comfortable.

Points to distinguish first

Chronic Pruritus: How to distinguish it from similar-looking skin diseases

What to look for on your skin now

Distinguish between initial skin changes and wounds caused by scratching.

When did it start and how has it recurred?

Chronic pruritus is a condition where itching lasts for 6 weeks or longer; rather than initial rashes, only linear marksscabor color changes from scratching may be visible. Causes can include not only skin issues like dryness, eczema, or scabies, but also new medications, liver, kidney, thyroid, diabetes, blood disorders, and neurological problems. Therefore, systemic distribution, medical history, and necessary tests are organized first. For itching that persists even after the cause is screened, the direction of body heat, dryness, sleep, digestion, and fatigue is analyzed through pattern identification (Byeonjeung). This information is reviewed again when determining the current stage and treatment boundaries of chronic pruritus.

Check what changes during treatment

Record systemic or localized distribution, differences between day and night, and areas that are not itchy.

Why does it keep getting worse?

Reasons why chronic pruritus persists or recurs

We do not overlook systemic causes first

Determine the scope of evaluation, including new medications and liver, kidney, thyroid, diabetes, or blood disorders.

What appeared on the skin before the itching started?

Distinguish between primary rashes and scratch wounds, and record systemic or localized distribution.

Observe if you wake up less during the night and if scratch wounds decrease

Monitor not only the itching score but also the number of times you wake up at night and the appearance of new wounds.

Things to prepare before your visit

What photos and records should I prepare before the medical evaluation?

Skin surface

We ask whether the itching came first, or if red plaques, wheals, or blisters appeared first. If only linear scratch marks and scabs are present, it is difficult to determine the cause based on skin appearance alone.

Distribution and timing

Record whether it is systemic or limited to one side or area, whether the back (where hands cannot reach) is also itchy, and how it changes after nighttime, showering, or exposure to heat.

Skin causes

Confirm dryness, eczema, hives, scabies, tinea, and contact exposure through examination.

Changes to monitor during treatment

What changes should I monitor during treatment?

Map of itchy areas and the sequence of initial skin changes versus scratch wounds

Please record when it started and how it has changed, including the dates. To make it easier to compare before and after, take photos of the same area from a similar distance and under similar lighting.

Medications, supplements, systemic diseases, and test results

Please leave a brief note. Compare not only the visible changes but also whether your sleep, pain, and daily life have become less uncomfortable.

Number of times waking up at night and changes after heat, showering, dryness, sleep, or digestion

Please also include the dates of any medications, ointments, or procedures you are currently using. This makes it easier to compare what led to improvement or worsening.

Lichen simplex chronicus often leaves coarse and thick skin lines in one area that has been scratched for a long time. We check if the urge to scratch occurs at night or during times of stress.

When planning herbal medicine treatment

Chronic Pruritus: The direction of herbal medicine treatment is determined based on your current prominent symptoms

Even if there are few distinct skin changes, skin temperature, dryness, scratch marks, and overall body condition vary by individual.

Pattern identification (Byeon-jeung) in Korean medicine is not about giving a different name to a disease. Multiple patterns can overlap in one person, and as the skin changes, for example, as oozing and heat decrease and dryness or cracking remain, the prescription is adjusted accordingly.

01 · Blood Heat · Febrile Itching

When itching is red and hot after exposure to heat or showering

Primary skin observations: We check if vivid redness and a sensation of heat remain over a wide area after scratching.
Overall body condition to check alongside skin: We check for thirst, heat in the upper body, and difficulty sleeping.
Primary considerations for herbal medicine prescription: The focus is on nourishing the blood and clearing heat to lower skin temperature and hypersensitivity.

02 · Blood Deficiency-Wind-Dryness / Dryness Type

When the skin is dry and itching worsens at night

Primary skin observations: We look for fine scales, cracks, and dry scratch marks.
Overall body condition to check alongside skin: We ask about dryness of the mouth and eyes, sensitivity to cold, and fatigue.
Primary considerations for herbal medicine prescription: The focus is on nourishing the blood, moisturizing dryness, and restoring the skin barrier and sleep.

03 · Damp-Heat Accumulation Type

When itching is worse in skin folds and the torso after sweating or exposure to humidity

Primary skin observations: We check for redness, skin breakdown, and a secondary infection (a 2nd infection) in damp areas.
Overall body condition to check alongside skin: We check for a feeling of heaviness in the body, bloating, and worsening symptoms after alcohol consumption.
Primary considerations for herbal medicine prescription: The focus is on reducing damp-heat, while first confirming the presence of infection.

04 · Qi and Blood Deficiency · Poor Recovery Type

When itching persists for a long time after an illness or during periods of fatigue

Primary skin observations: We check if wounds heal slowly and discoloration lasts a long time without significant redness.
Overall body condition to check alongside skin: We ask about loss of appetite, lack of sleep, and chronic fatigue.
Primary considerations for herbal medicine prescription: The focus is on supplementing Qi and blood and restoring digestion and immunity.

How is the herbal medicine prescription adjusted?

Identifying the cause takes priority over pattern identification
We identify causes related to the skin, medications, systemic conditions, or neurological factors.
We determine whether the primary focus should be heat and dryness, humidity, or recovery
Determine the overlapping weight for one person.
Adjust the prescription based on the number of times you wake up during sleep and any new scratch marks.
Observe whether the itching time, nighttime awakenings, and new wounds decrease together.

When should I consider Korean herbal medicine treatment?

When generalized itching and nighttime awakenings persist for more than 6 weeks even after a cause evaluation
When scratching resumes immediately after pausing antihistamines or moisturizing treatments
When dryness, heat, sleep, digestion, and fatigue fluctuate along with the itching

What will be asked during the medical evaluation?

A map of the itchy areas and the sequence of initial skin changes and scratch marks
Current medications, supplements, systemic diseases, and test results
The number of times you wake up at night and changes following heat, showering, dryness, sleep, or digestion

If pus, pain, or redness spreads rapidly, or if you have a fever, lesions inside the eyes or mouth, shortness of breath, or sudden facial swelling, please visit a dermatology clinic or seek emergency care first. After confirming that such urgent situations are not present, Baekrokdam provides herbal medicine treatment for chronic and recurring skin diseases.

Frequently Asked Questions

Frequently Asked Questions about Chronic Pruritus

Do I need medical evaluation for pruritus even if there is no rash?

Yes. For long-term itching, it is necessary to check not only skin dryness and skin diseases but also medications, systemic diseases, and neurological issues. The required examinations and tests are determined based on the distribution, duration, and accompanying symptoms.

Why are antihistamines not working well?

Not all itching is caused by histamine alone. Since responses can vary depending on whether the cause is dryness, neurological issues, or systemic diseases, the causes must be differentiated first.

What should I record before the medical evaluation?

Please prepare a map of the itchy areas, the time when it is most severe, the relationship with showering, heat, food, or medication, the number of times you wake up during sleep, and a list of medications and supplements.

What is evaluated in Korean herbal medicine treatment?

After ruling out potential causes, we determine the priority of the prescription by observing whether heat sensations, dryness, nighttime worsening, sleep, digestion, and fatigue fluctuate in tandem with the actual itching.

What should I record before a consultation for chronic pruritus?

A map of the itchy areas and the sequence of initial skin changes and scratch marks, current medications, supplements, systemic diseases and test results, the number of times you wake up at night, and changes following heat, showering, dryness, sleep, or digestion
