Where do dyshidrosis blisters mainly appear?

Small, deep blisters mainly appear on the palms, sides of the fingers, soles of the feet, and toes. If they spread widely to other areas or persist on only one side, other conditions are evaluated.

Do dyshidrosis symptoms remain even after the blisters disappear?

As blisters dry, the skin may peel, become dry, or develop deep cracks. If this repeats, the skin can thicken, and using your hands or feet may become painful.

Current discomfort

Foot Dyshidrosis, 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 foot dyshidrosis or another skin issue.

Those who notice an increase in sole blisters after hot weather, exercise, or wearing closed-toe shoes
Those who are unsure if they have athlete's foot between the toes or dyshidrosis
Those who find walking uncomfortable because the soles peel and crack after the blisters dry

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.

Frequently Asked Questions

Foot pompholyx: Are you curious about these points?

Are deep blisters on the soles of the feet pompholyx or athlete's foot?
If it occurs on only one foot, is a fungal test necessary?
How does herbal medicine treatment categorize the cycle of blisters and cracking in foot pompholyx?

Medical Evaluation GuideDistinguishing between rashes that disappear within hours and dermatitis that lasts for daysFirst, observe whether swelling in the same area generally fades without leaving a mark within a day, or whether it stays for several days, leaving dead skin, oozing, or scabs. Wheals that disappear and reappear in different locations suggest urticaria (hives), while long-lasting surface changes suggest other types of dermatitis; however, a diagnosis requires looking at the overall progression.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.

You can check the simple meaning first before proceeding to the detailed explanation

Terms used in the foot pompholyx guidance

VesicleVesicles refer to small blisters. Since causes vary, including dyshidrosis that forms deeply on the sides of fingers, contact dermatitis, or infections, we examine the location, pain, itching, and whether they appear in clusters.Fungal TestA fungal test is an examination that confirms a fungal infection by scraping off dead skin to view under a microscope or by culturing it if necessary.FissureFissures are a state where the skin is cracked, creating gaps, which can cause pain and bleeding on the hands, feet, or in skin folds.

When herbal medicine treatment is the primary focus

Foot pompholyx: If symptoms worsen again even after treatment

If the cycle of deep blisters on the hands and feet drying, peeling, and cracking repeats, managing only the affected area may leave a burden on your daily life. By dividing the changes into the vesicle stage and the dryness/fissure stage, the recurrence cycle can be managed, centered on Korean herbal medicine treatment.

Before the consultation

We ask where it appeared and when it worsened again

We examine the depth of the vesicles, feelings of heat, oozing, subsequent dryness and fissures, as well as sweat, stress, sleep, and the timing of recurrence.

During treatment

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

We compare the interval at which new vesicles appear, the degree of cracking and pain, limitations in the use of hands and feet, and the recovery period.

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.

Foot pompholyx: Symptoms and when to seek prompt medical evaluation

Foot pompholyx is a form of pompholyx on the feet where deep, small vesiclesblisters cluster on the soles and sides of the toes, causing itching or stinging. It may worsen with closed-toe shoes and sweat, but sweat alone is unlikely to be the sole cause. It is distinguished from athlete's foot (characterized by erosion between toes, fine scaling, and nail changes), palmoplantar psoriasis (characterized by thick, well-defined borders), and contact dermatitis (characterized by patterns matching the shoe material).

Symptom stages and next steps

Small vesicles, recovery phase cracks, and suspected infection symptoms are examined differently

Do not confirm a diagnosis based on appearance alone; check the location, recurrence cycle, pain, and heat sensation together.

Current Appearance	Points to Check	Next action
Deep, small vesicles on the sides of fingers or palms	Whether severe itching or burning occurred first	Do not scratch or pop; seek a dermatology diagnosis
Blisters merge to form a large blister	Whether it is difficult to use hands/feet or to walk	Seek prompt medical evaluation if the area is large or pain is severe
Peeling, dryness, or deep cracks following blisters	Whether new blisters continue to appear	Moisturize, avoid irritation, and re-evaluate treatment
Yellow crusts, pus, spreading erythema, and heat sensation	Whether pain, swelling, or fever are present	Seek prompt medical evaluation to check for infection
Persistent scaling or blisters on only one foot	Nail changes · Dead skin between toes	Examination for other conditions such as athlete's foot

Director Choi Yeon-seung's Clinical Perspective

Dyshidrotic eczema of the feet: How is the direction of Korean herbal medicine treatment determined?

If there are acute changes such as pus, yellow scabs, spreading heat sensation and pain, fever, large blisters, or changes in mucosal skin, dermatology or emergency evaluation and necessary treatment for infections or blistering diseases take priority over Baekrokdam Korean herbal medicine treatment. If small blisters and cracking repeat chronically despite maintaining diagnosis and standard topical treatments, please record your exposure to water, detergents, gloves, and sweat, as well as nighttime itching and changes in hand/foot usage, to consult on the goals of Korean herbal medicine treatment.

Changes to be confirmed in this treatmentWe aim to shorten the cycle of new blisters and peeling, and increase the interval between recurrences and the days you can walk without cracking.

Small, deep blisters on the sides of the fingers or palms are important clues for pompholyx. Since it can overlap with athlete's foot or contact dermatitis, we examine whether it is severe on only one side and consider exposure factors.
Actual clinical photos and educational close-up examples are materials for comparing possible patterns and cannot be used for diagnosis alone. Mechanism diagrams have simplified complex processes.

Palmoplantar psoriasis significantly interferes with walking, gripping, and working with water, even if the affected area is small. We compare bilateral distribution, fungal tests, and nail clues with hand eczema and tinea manuum.

Points to distinguish first

Dyshidrotic eczema of the feet: How to distinguish it from similar-looking skin diseases

First, check if there is pain, suppuration, heat, or blisters of a different shape

Check for unilateral distribution, pus, heat, fever, large blisters, or changes in mucosal skin, and do not delay necessary dermatological examinations and treatment.

Distinguish between when new blisters appear and when the skin peels and cracks

Specifically identify the current skin stage by recording itching before blisters, the number of new blisters, and cracking and pain after they dry.

Check the interval between new blisters and the days when your hands and feet feel less uncomfortable

Do not arbitrarily stop using prescribed topical medications; observe if the number of days without new blisters changes in relation to sleep, typing, water-related work, or walking.

Why does it keep getting worse?

Reasons why dyshidrotic eczema of the feet persists or recurs

We separately verify the appearance of new blisters and the level of pain when walking

If walking remains difficult due to cracking even if the number of blisters decreases, the treatment stage is not yet complete.

We examine skin reactions differently for hot and humid conditions versus cold conditions

The direction of regulating body heat and humidity varies depending on whether symptoms increase when the feet are hot and wet, or if the skin changes feel hot despite a general feeling of coldness.

If symptoms are severe on only one hand or foot, or if athlete's foot is present, we check for fungal infection

If there is dominant keratinization on one side, erosion between the toes, or changes in the nails, we first arrange for the necessary fungal evaluation.

Educational example of tinea manuum showing relatively wide fine keratinization and white keratin along the skin lines on one palm of an adult — 03 · View with main textProminent pattern of tinea manuum on one hand
Tinea manuum can appear as fine scaling that is more severe on one hand, which can be confused with hand eczema. We consider accompanying athlete's foot and fungal tests together.

Things to prepare before your visit

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

Please prepare the date and photos of the area where the blisters first appeared, information on nighttime itching, presence of discharge or pus, exposure to water, detergents, gloves, or sweat, and your current topical medications and medical evaluation results.

Deep blisters on the sides of the toes

Dyshidrosis can present as small, transparent blisters that gather under the skin, then dry and peel.

Sores between toes and nail changes

Clues for athlete's foot include scaling and sores between the toes, changes in the fingernails or toenails, and a distribution that is more dominant on one side.

Boundary of shoes and socks

We check if the boundary of the rash matches the area in contact with shoe rubber, adhesives, or dyes.

Changes to monitor during treatment

What changes should I monitor during treatment?

Starting location of blisters on both feet

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.

Timing of new blisters in relation to shoes, exercise, and sweat

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

Degree of walking discomfort due to peeling and cracking

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.

When planning herbal medicine treatment

For foot dyshidrosis, the direction of herbal medicine treatment is determined based on your current prominent symptoms

Even for the same case of foot dyshidrosis, the direction of herbal medicine treatment is determined by observing current skin changes and whether sleep, digestion, and fatigue levels are also changing.

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 · Damp-Heat · Active Inflammation

When redness, heat, oozing, and swelling are prominent

Primary skin observations: We examine the redness, heat sensation, discharge, and the speed of spreading of the skin changes in foot dyshidrosis.
Overall body condition to check alongside skin: We check if itching increases and sleep is disrupted after exposure to heat, sweat, or humid environments.
Primary considerations for herbal medicine prescription: We first reduce the burden of active inflammation, damp-heat, and intense itching.

02 · Blood Deficiency and Wind-Dryness · Barrier Damage

When the skin is dry, thickened, and cracks even with minor irritation

Primary skin observations: We check if dead skin, lichenification, cracking, and discoloration persist for a long time, even if there is little discharge.
Overall body condition to check alongside skin: We ask about tightness after washing, nighttime itching, and whether wound healing is delayed.
Primary considerations for herbal medicine prescription: We increase the focus on nourishing the blood, moisturizing dryness, and restoring the skin barrier.

03 · Spleen deficiency-dampness accumulation · Delayed recovery

When swelling, dampness, digestive issues, and fatigue occur on the same day during activity

Primary skin observations: We check if blurred boundaries, damp dead skin, or swelling persist for a long time.
Overall body condition to check alongside skin: We check if bloating, loose stools, and heavy fatigue repeatedly overlap with the worsening of the skin.
Primary considerations for herbal medicine prescription: Rather than just drying the skin, we simultaneously look at the recovery of the spleen, stomach, and fluid metabolism.

04 · Qi stagnation · Body heat fluctuations

When heat sensations and itching surge after tension or lack of sleep

Primary skin observations: Rather than the shape of skin changes, we look at the time of day when redness and scratching suddenly increase.
Overall body condition to check alongside skin: We check if feelings of oppression, upper body heat, and poor sleep start before the skin symptoms.
Primary considerations for herbal medicine prescription: We add a focus on regulating body heat and tension responses to reduce the extent of worsening and the delay in recovery.

How is the herbal medicine prescription adjusted?

We first examine the symptoms that are currently most uncomfortable
Dyshidrotic eczema of the feet is characterized by clusters of deep, small blisters on the soles and sides of the toes, accompanied by itching or tingling. It may worsen with closed-toe shoes and sweat, although sweat alone is rarely the sole cause. It must be distinguished from athlete's foot (which involves maceration between toes, fine scaling, and nail changes), palmoplantar psoriasis (which presents as thick, well-defined plaques), and contact dermatitis (which follows the shape of the shoe material).
We also ask about changes in your overall body condition that occurred on the same day as the skin changes
The approach to regulating body heat and moisture differs depending on whether symptoms increase when the feet are hot and wet, or if the skin changes are hot despite a general feeling of coldness.
We adjust the prescription at the next visit according to the changes in symptoms
We aim to shorten the cycle of new blisters and peeling, and increase the interval between recurrence and the days you can walk without cracking.

When should I consider Korean herbal medicine treatment?

When blisters on the soles of the feet recur after exercise or heat, even when using topical agents
When it is difficult to walk or stand for long periods due to peeling and cracking
When the cycle of deep blisters continues despite treatment for athlete's foot

What will be asked during the medical evaluation?

Starting location of blisters on both feet
Timing of new blisters in relation to shoes, exercise, and sweat
Degree of walking discomfort due to peeling and cracking

Things to prepare before the consultationPlease prepare the date and photos of the area where the blisters first appeared, information on nighttime itching, presence of discharge or pus, exposure to water, detergents, gloves, or sweat, and your current topical medications and medical evaluation results.

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 foot dyshidrosis

Where do dyshidrosis blisters mainly occur?

Small, deep blisters mainly appear on the palms, sides of the fingers, soles, and toes. If they spread widely to other areas or persist on only one side, other conditions are checked.

Do dyshidrosis symptoms remain after the blisters disappear?

As the blisters dry, the skin may peel, become dry, or develop deep cracks. If this repeats, the skin may thicken, and pain may occur when using the hands and feet.

Is it an infection if there is discharge from pompholyx blisters?

Discharge alone does not confirm an infection, but if there are yellow crusts, pus, spreading redness with heat, pain, or fever, a bacterial infection must be promptly checked.

Is pompholyx caused by excessive sweating?

While excessive sweating and damp hands or feet can worsen the condition, blocked sweat glands are not the confirmed cause.

Could a metal allergy be the cause?

Hypersensitivity to nickel or cobalt may be involved. A dermatologist evaluates the relationship between exposure and recurring symptoms.

Is stress the cause?

Stress may be a factor in worsening or triggering the condition, but a patient's emotions alone are not viewed as the sole cause.

Should I also check for athlete's foot?

If foot peeling and itching occur together, testing is considered to determine if it is a reaction related to a fungal infection.
