Palmoplantar and nail psoriasis: Start with your questions
Points to check first
Palmoplantar and nail psoriasis: Symptoms and when to seek prompt medical evaluation
Palmoplantar psoriasis presents as thick, well-defined plaques of keratin in pressure areas of the palms and soles, crackingwhile nail psoriasis may appear as small pits, yellowish-brown oil-drop spots, lifting, or crumbling. It is distinguished from the deep blisters of pompholyx, tinea pedis/manuum on one hand or foot, and nail fungus; joint pain, swelling, and morning stiffness in the fingers and toes are also checked.
Distinguishing types and emergencies
Determine when to seek medical evaluation based on the appearance of the skin and symptoms appearing on the nails, joints, and throughout the body
Consider the location, function, and general body condition, rather than looking only at the area of skin change.
| Visible or felt symptoms | What to check | Priority action |
|---|---|---|
| Thick, raised plaques and silvery-white scales | Possibility of plaque psoriasis | Document distribution, itching, and cracking |
| Small drop-shaped skin changes on the torso and limbs | Possibility of guttate psoriasis | Recent Infections and Skin Care |
| Smooth rash in armpits or groin | Possibility of inverse psoriasis (skin folds) | Differentiate from friction or infection |
| Nail pitting, thickening, and joint swelling | Possibility of nail psoriasis or psoriatic arthritis | Prompt medical evaluation by dermatology or rheumatology |
| Generalized redness, widespread pustular skin changes, or fever | Possibility of severe psoriasis | Immediate hospital evaluation |
Pitting, oil-drop discoloration, and lifting are clues for nail psoriasis, but fungal infections and trauma can appear similar. Joint pain and swelling are also checked.
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.If these discomforts have recurred
For those experiencing pain when gripping or walking due to palm cracking and nail changes
Psoriasis of the hands and feet cannot be lightly assessed based solely on a small affected area. We analyze active heat, thick fissures, nail changes, and joint clues, as well as the relationship between sleep, fatigue, digestion, and recovery. Byeonjeung (pattern identification).
Those who experience thick keratin plates and fissures on the palms or soles that recur in the same pressure-bearing areas
Keratin removaltopical agents When the same pressure-bearing areas of the hands or feet crack again afterward
Those whose nail pitting, lifting, or crumbling is not explained by athlete's foot treatment
When pitting, lifting, or crumbling increases across multiple nails despite treatment for nail fungus
Those who have both skin changes and pain or swelling in the finger or toe joints
When discomfort in the finger and toe joints increases along with walking, gripping, or working with water
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.
Points to distinguish first
How to distinguish palmoplantar and nail psoriasis from similar-looking skin diseases
Please also let us know if your joints are stiff or if your eyes are painful
We screen for extensive redness, pus, fever, joint swelling and stiffness, as well as eye pain and changes in vision.
Please inform us about your nails and joints as well as your skin
We record photos taken under the same conditions, as well as the sequence of onset for scales, cracking, and nail or joint symptoms.
We check if both the skin and daily life are improving together
While maintaining dermatology or rheumatology treatments, we observe changes in itching, sleep, work, and joint function.
Why does it keep getting worse?
Reasons why palmoplantar and nail psoriasis persist or recur
First, we distinguish it from infections and dyshidrotic eczema
We check for blisters, unilateral distribution, fungal test results, and nail changes.
Please let us know if walking, gripping, or working with water is difficult, even if the affected skin area is small
We also monitor whether fissure pain decreases and whether daily activities, such as walking or working with water, become more comfortable.
Please be sure to tell us if your joints are swollen or stiff
If there is swelling, pain, or stiffness in the fingers and toes, we will proceed with an evaluation for psoriatic arthritis.
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 photos of your skin, scalp, and nails, and information regarding itching, cracking, bleeding, joint swelling, morning stiffness, heel pain, and your response to previous treatments.
Palms and Soles
You may see thick plaques and cracks in pressure areas, and you may feel pain when doing water-related work, walking, or using tools.
Nails
We record how many nails are affected by pitting, oil-drop discoloration, lifting, or crumbling, and the order in which these appeared.
Blisters
If deep, small blisters on the sides of the fingers and palms appeared first, we also evaluate for dyshidrotic eczema.
Changes to monitor during treatment
What changes should I monitor during treatment?
Photos of both hands, both feet, and the deepest fissures
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.
Blisters, fungal test results, foot athlete's foot, and the sequence of nail changes
Please leave a brief note. Compare not only the visible changes but also whether your sleep, pain, and daily life have become less uncomfortable.
Joint swelling, morning stiffness, and ability to walk or do water-related chores
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.
Psoriasis is evaluated by looking at the borders of the plaques, the layered scales, and the distribution, such as on the elbows and knees. Changes in the nails and joint discomfort are also checked separately from the skin photos.
When planning herbal medicine treatment
Palmoplantar and nail psoriasis: the direction of herbal medicine treatment is determined based on the most prominent current symptoms
Symptoms are categorized into red and hot new plaques, thick and dry fissures, or long-standing dark red plaques with nail changes.
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.
When red, hot plaques and new fissures increase
- Primary skin observations
- We examine for vivid erythema, heat sensation, and newly developed skin changes.
- Overall body condition to check alongside skin
- We check for worsening after heat exposure, alcohol consumption, or lack of sleep.
- Primary considerations for herbal medicine prescription
- Focus on nourishing the blood and clearing heat to reduce immune overactivation and skin heat.
When skin is thick, dry, cracked, and pain is severe
- Primary skin observations
- We examine the thickness of keratin, fissures, bleeding, and dryness of the nails.
- Overall body condition to check alongside skin
- We ask about dryness of the skin and mouth, fatigue, and delayed recovery.
- Primary considerations for herbal medicine prescription
- The focus is on nourishing the blood, moisturizing dryness, and restoring the skin barrier.
When long-standing dark red plaques and nail changes become fixed
- Primary skin observations
- We examine for dark coloration, thickness, nail lifting, and pain.
- Overall body condition to check alongside skin
- We check for joint stiffness, coldness, and the long-term progression of the condition.
- Primary considerations for herbal medicine prescription
- Blood circulation and recovery support are added to the regulation of heat and dryness.
When redness, heat, oozing, and swelling are prominent
- Primary skin observations
- We examine the redness, heat sensation, exudate, and the speed of spreading of skin changes in palmoplantar and nail psoriasis.
- 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.
How is the herbal medicine prescription adjusted?
- Infections and blistering diseases are ruled out first
Necessary bacterial tests and differentiation from dyshidrotic eczema are prioritized.
- Skin, nails, and joints are tracked in a single record
We observe whether the progression speed differs across these three areas.
- Prescriptions are adjusted based on improvements in walking and hand use
Along with the number of fissures, we check if walking, gripping, and doing water-related chores become easier.
When should I consider Korean herbal medicine treatment?
- When the same pressure points on the hands and feet crack even after keratin removal and use of topical agents
- When pitting, lifting, or crumbling increases across multiple nails despite treatment for nail fungus
- When discomfort in the finger and toe joints increases along with walking, gripping, or doing wet work
What will be asked during the medical evaluation?
- Photos of both hands, both feet, and the deepest cracks
- Order of blisters, fungus tests, athlete's foot, and changes in fingernails/toenails
- Joint swelling, morning stiffness, and function during walking or wet work
Things to prepare before the consultationPlease prepare photos of your skin, scalp, and nails, and information regarding itching, cracking, bleeding, joint swelling, morning stiffness, heel pain, and your response to previous treatments.
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 about palmoplantar and nail psoriasis
Where does psoriasis usually occur?
It is common on the scalp, elbows, knees, and torso, but it can appear anywhere, including the palms, soles, skin folds, and nails.
Is it okay to pick at psoriasis scales?
Forcing them off can cause cracking, bleeding, and skin damage. Manage them according to your prescribed treatment and moisturizing plan.
Are nail pits also a symptom of psoriasis?
Small pits, thickening, crumbling, or lifting may occur. A medical evaluation is necessary to differentiate this from conditions such as fungal infections.
If my joints are stiff, should I wait until the skin condition worsens?
Do not wait. Joint swelling, morning stiffness, or swelling of the entire fingers and toes require prompt medical evaluation to prevent joint damage.
What is the root cause of psoriasis?
Genetic predisposition and environmental factors both play a role in a process where skin cells are produced too quickly due to overactivation of the immune system.
Can psoriasis develop where there is an injury?
Skin changes can occur in the same spot after injuries such as cuts, burns, or severe scratching, so please record the timing of the injury and the appearance of the rash.
If I feel the medication is making it worse, should I stop taking it?
Do not stop prescribed medication arbitrarily; instead, show the prescriber the medication name, start date, dosage changes, and photos of your skin.
