What Causes Rashes on Palms and Soles?
There are many possible causes for rashes on the palms and soles. Some of the most common include:
Eczema
Eczema, also known as atopic dermatitis, is a skin condition characterized by itchy, red, and dry skin. It often affects the hands and feet. Eczema can cause red, scaly, thickened skin on the palms and soles. Flare-ups can occur in response to certain triggers like stress, irritants, allergens, and changes in temperature.
Psoriasis
Psoriasis is an autoimmune condition that causes a buildup of skin cells that leads to red, scaly patches. Between 30-50% of people with psoriasis have it on their palms and soles. The rash often has a thick, plaque-like appearance.
Allergic Contact Dermatitis
This refers to a rash caused by an allergy to something touching the skin. On the hands and feet, it can occur in response to chemicals, metals like nickel, rubber products, topical medications, and more. The rash often appears as red, itchy, swollen skin.
Dyshidrotic Eczema
Also known as dyshidrosis or pompholyx, this type of eczema causes blisters to form on the palms, sides of the fingers, and soles. It is often triggered by factors like seasonal allergies, stress, sweat, and contact with irritants.
Scabies
Scabies is an infestation of the skin by tiny mites. When they burrow into the skin, they can cause an intensely itchy rash with bumps or blisters. Scabies commonly affects the palms and between the fingers.
Ringworm
Ringworm is a fungal infection of the top layer of skin. When it affects the palms or soles, it often has a ring-like red, scaly appearance. Ringworm is highly contagious and can be passed through direct skin contact or contact with contaminated surfaces or objects.
Syphilis
Syphilis is a sexually transmitted bacterial infection. In its secondary stages, syphilis can cause a rash on the palms and soles that resembles rough, reddish-brown calluses. The rash is often accompanied by flu-like symptoms.
Symptoms Associated with Palmar and Plantar Rashes
In addition to a visible rash, other symptoms may occur including:
- Redness
- Scaling and thickening of skin
- Flaking or peeling skin
- Small blisters or bumps
- Itching or burning sensation
- Cracking of skin
- Pain, tenderness or soreness
- Dryness and inflammation
- Oozing or crusting
When to See a Doctor
In many cases, rashes on the hands and feet can be managed at home with over-the-counter treatments and home care. However, it's a good idea to see your doctor if:
- The rash is severe, widespread, or rapidly worsening
- Symptoms are interfering with daily activities
- You experience fever, chills, or flu-like symptoms
- The rash does not improve with self-care after 1-2 weeks
- You are unsure of the cause
- You have other concerning symptoms like joint pain, fatigue, or swelling of lymph nodes
Seeking timely medical care is important to get proper treatment and avoid any complications. Diagnostic tests may be recommended to determine the underlying cause.
Treatments and Home Remedies
Treatment will depend on the specific cause of the rash. Some general treatment options include:
Medicated Ointments and Creams
Over-the-counter and prescription topical ointments can help reduce inflammation, itching, pain, and other symptoms. This may include corticosteroid creams, antifungal ointments, immune-modulating creams, and moisturizers.
Oral Medications
For moderate to severe rashes, oral prescription medications may be used. These can include antihistamines, antifungals, antivirals, steroid pills, and immune-modulating drugs.
Light Therapy
For some conditions like psoriasis, exposing the affected skin to UV light under medical supervision can help improve symptoms.
Wet Wraps
Wet wrap therapy involves first applying topical medications, then wrapping the area with wet bandages covered by a dry outer layer. This can reduce itching and help topicals absorb better.
Avoid Irritants and Triggers
Avoiding things that seem to worsen your rash, like harsh soaps, fragrances, hot water, abrasive materials, and skin irritants can help prevent flare-ups.
Gentle Skin Care
Use mild cleansers, moisturize regularly, take shorter showers, and avoid vigorously rubbing or scrubbing the affected skin.
Oatmeal Baths
An oatmeal bath can help soothe itchy, inflamed skin and provide relief from rash symptoms.
Cold Compresses
Applying a cool, wet compress to the rash for 10-15 minutes a few times a day can provide comforting relief from discomfort.
When to Try Natural Remedies
For mild rashes, you may try using natural remedies for a few days to see if symptoms improve, including:
- Coconut oil - Has moisturizing and anti-inflammatory properties
- Apple cider vinegar - Can reduce bacteria and balance skin pH
- Aloe vera gel - Soothes inflamed skin
- Oregon grape root - Has antimicrobial and anti-inflammatory effects
- Tea tree oil - Has antifungal properties (dilute before applying!)
- Turmeric paste - Has antioxidant and anti-inflammatory properties
Always do a patch test before applying new topicals to make sure you don't have a bad reaction. Talk to your doctor before using natural remedies if you are already taking medications.
When to Avoid Natural Treatment
While natural remedies can be helpful for some mild skin conditions, they are not a substitute for medical treatment. You should avoid trying to treat a rash naturally if:
- The rash is severe or rapidly spreading
- You have a fever, joint pain, or other concerning symptoms
- You have a compromised immune system
- The rash persists longer than 2 weeks
- Your symptoms are significantly impacting your daily life
- You have diabetes or poor circulation in the affected area
- You are unsure of the cause
Some natural ingredients may interact with medications or make certain skin conditions worse, so check with your dermatologist before using them.
Prevention Tips
While you can't always prevent rashes completely, the following measures can help reduce your risk:
- Moisturize hands and feet daily

- Wear gloves for wet work and rough cleaning
- Treat pre-existing skin conditions properly
- Wear breathable socks and shoes

Keep your skin in the best condition possible and avoid excess irritation to help prevent troubling rashes.
When to See a Dermatologist
If you have ongoing issues with rashes on your palms and soles, make an appointment with a dermatologist. A skin specialist can:
- Properly diagnose the cause
- Prescribe stronger medications as needed
- Provide specialized treatments
- Test for allergies or infections
- Monitor your condition long-term
- Help prevent recurrent rashes
Getting expert care can help resolve stubborn rashes and prevent complications. Don't hesitate to see a professional skin doctor if over-the-counter methods fail.
