How can I tell foot psoriasis from athlete’s foot?

Psoriasis tends to make thick, sharply edged patches on both soles, often with psoriasis elsewhere, such as the elbows, knees or scalp. Athlete’s foot usually starts between the toes with itchy, peeling, soggy skin, or causes fine scaling on one foot more than the other, and it improves with antifungal cream. A doctor can scrape a little skin to check for fungus.

What is the best treatment for psoriasis on the feet?

Most people start with thick moisturizers, a urea or salicylic acid cream to soften scale, and a prescription steroid or vitamin D cream. The skin on the soles is thick, so doctors often use stronger creams there than elsewhere. If creams aren’t enough, light therapy, pills or injected biologic medicines can work very well.

Is psoriasis on the feet contagious?

No. Psoriasis is caused by an overactive immune system, not an infection, so you can’t catch it or pass it on. The pus-filled bumps of pustular psoriasis on the soles are not infected either, although cracked skin can become infected.

Why does psoriasis on my feet crack and bleed?

Psoriasis makes the skin thick and stiff, and the soles bend and take your weight with every step, so the skin splits. Softening the scale with urea or salicylic acid creams, moisturizing twice a day and using your prescribed treatment all help. See a doctor if cracks are deep, bleeding often or look infected.

Can psoriasis affect toenails?

Yes, nail changes are common in people with psoriasis. Toenails can develop small pits, yellow-brown patches, thickening, crumbling or lifting, which looks a lot like nail fungus. A nail clipping test tells them apart, and nail changes can be an early sign of psoriatic arthritis.

What are the signs of psoriatic arthritis in the feet?

Common signs are a whole toe that swells up like a sausage, pain at the back of the heel or under the heel, and stiff, painful joints that are worse in the morning. If you have psoriasis and notice these, see a doctor soon, because early treatment can prevent lasting joint damage.

Can I use athlete’s foot cream on psoriasis?

It won’t help unless you also have a fungal infection. Antifungal creams treat fungus, while psoriasis needs moisturizers and anti-inflammatory treatment. If an antifungal cream hasn’t helped a scaly foot rash after 2 weeks, have it checked for psoriasis or eczema.

Psoriasis on feet: symptoms, treatment and daily care

How psoriasis shows up on the soles and toenails, how to tell it from athlete’s foot, which treatments work, and daily care that eases painful cracks.

The short answer

Psoriasis on the feet usually shows up as thick, dry, sharply edged patches on the soles, often with silvery-white scale and painful cracks. Some people get small pus-filled bumps on the soles instead, or thick, pitted, discolored toenails. It isn’t contagious, and it’s often mistaken for athlete’s foot.

Treatment usually starts with thick moisturizers, creams that soften scale, and prescription steroid or vitamin D creams. Stubborn cases may need light therapy or medicines that calm the immune system. See a doctor if cracks bleed or look infected, walking hurts, or your toes or heels become swollen and painful, which can be a sign of psoriatic arthritis.

What does psoriasis on the feet look like?

Psoriasis is a long-term condition in which an overactive immune system makes skin cells build up far faster than normal. On most of the body that causes raised, scaly patches called plaques. On the feet, where the skin is thick and takes your weight, it can look a little different. There are three main types:

Plaque psoriasis on the soles. Thick, dry patches with sharp edges, often with silvery-white scale. They’re usually on both soles, especially the heels and the ball of the foot, and they often crack. On lighter skin the patches look red or pink; on darker skin they may look purple, brown or gray.
Palmoplantar pustulosis. Small yellow-white bumps filled with pus appear on the soles, often the arch and heel, and sometimes the palms. They dry into brown spots and peel. The pus is not an infection. This type is strongly linked to smoking.
Nail psoriasis. Toenails can develop small pits, yellow-brown patches, thickening, crumbling or lifting.

Many people also have patches elsewhere, such as the elbows, knees, lower legs, scalp or lower back.

What causes psoriasis on the feet?

Psoriasis runs in families, and it isn’t caused by poor hygiene or an infection. It isn’t contagious. People who have the genes for it tend to have flare-ups set off by triggers, such as:

injury to the skin, including friction from shoes, blisters and scratching, which can cause new patches in the injured spot
stress
infections, such as strep throat
smoking and heavy drinking
cold, dry weather
some medicines, such as lithium, some blood pressure medicines (beta-blockers) and antimalarials

Don’t stop a prescribed medicine on your own. If you think one is making your psoriasis worse, talk to the doctor who prescribed it.

Psoriasis vs athlete’s foot vs eczema

These three are often confused, and the treatments are different:

Feature	Psoriasis	Athlete’s foot	Eczema
Where	Soles and heels, usually both feet	Between the toes, or the sole and sides in a moccasin pattern, often one foot more than the other	Sides of the toes and soles (tiny blisters), or the top of the foot where shoes touch
What you see	Thick patches with sharp edges and silvery scale, painful cracks, sometimes pus bumps	Peeling, soggy white skin between the toes, or fine powdery scale	Tiny, very itchy blisters, or red, dry, less sharply edged patches
Other clues	Patches elsewhere, pitted nails, family history	Thick, discolored toenails from nail fungus	Hay fever, asthma or eczema elsewhere, or a new shoe or sock material
What helps	Moisturizers, steroid and vitamin D creams, other psoriasis treatment	Antifungal cream	Moisturizers, steroid creams, avoiding triggers

Because they look alike, it’s worth getting a diagnosis if a scaly rash on your feet doesn’t clear. A doctor will examine your skin and nails, ask about family history and may scrape a little skin to check for fungus. A small skin biopsy is sometimes needed. If you think it might be fungal, our guide to athlete’s foot creams explains the options.

Treatment for psoriasis on the feet

There’s no cure for psoriasis, but treatment can clear or greatly improve it. Psoriasis on the soles can make walking painful, so doctors often treat it more seriously than its size alone would suggest.

Creams and ointments

Thick moisturizers such as ointments or heavy creams, used at least twice a day, soften skin and help prevent cracks.
Scale-softening creams with urea or salicylic acid thin down thick scale so other treatments can reach the skin. If you have diabetes or poor circulation, ask your doctor before using salicylic acid on your feet.
Steroid creams and ointments calm inflammation. The skin on the soles is thick, so doctors often prescribe stronger ones than they’d use elsewhere, sometimes covered with plastic wrap or a sock overnight to help them soak in. Over-the-counter hydrocortisone is usually too weak for the soles. Use strong steroids only as prescribed.
Vitamin D creams, such as calcipotriene, slow skin cell growth and are often combined with a steroid.
Coal tar products can help scale and itching, though they smell and can stain.

Light therapy

Controlled doses of ultraviolet light, given in a clinic, can help psoriasis on the hands and feet. Options include targeted UVB and PUVA, where a medicine called psoralen is applied or taken first to make the skin more sensitive to UVA light. Treatment is usually several times a week for a number of weeks. Tanning beds are not a substitute.

Medicines that work throughout the body

If creams and light therapy aren’t enough, a dermatologist may prescribe pills or injections that calm the immune system, such as methotrexate, apremilast, or acitretin, an oral retinoid often used for psoriasis on the soles. Biologic medicines, given by injection, include adalimumab, secukinumab, ixekizumab, guselkumab and risankizumab. These can work very well, but they need regular monitoring, and some aren’t safe in pregnancy. Your doctor will talk through the benefits and risks.

Toenail psoriasis

Nail changes are common in people with psoriasis. On the toenails you may notice:

small pits or dents in the nail surface
yellow-brown or salmon-colored patches, sometimes called oil drops
the nail lifting away from the skin underneath
thickening, with crumbly debris under the nail

These changes look a lot like nail fungus, and you can have both at once, so a nail clipping test is worth doing before treatment. Nail psoriasis is treated with strong creams around the cuticle, steroid injections into the skin beside the nail, or the medicines above. Improvement is slow because toenails take 12 to 18 months to grow out. Meanwhile, a podiatrist can thin and trim thick nails so they don’t press in your shoes. Learn more about nail care at Evolve Health, and see our guide to toenail fungus treatment if a test shows fungus.

Psoriatic arthritis in the feet

Up to about 1 in 3 people with psoriasis develop psoriatic arthritis, which inflames the joints and the places where tendons and ligaments attach to bone. The feet are often affected. Watch for:

a sausage toe, where a whole toe swells up
heel pain, at the back of the heel where the Achilles tendon attaches, or under the heel (our guide to heel pain in the morning covers other causes)
stiff, painful, swollen joints, often worse in the morning or after rest
nail changes, which make psoriatic arthritis more likely

If you have psoriasis and notice any of these, see a doctor soon. Early treatment, usually led by a rheumatologist, can prevent lasting joint damage. A podiatrist can help with the foot side: supportive shoes, custom orthotics to take pressure off painful areas, and care for arthritic conditions of the foot and ankle.

Daily care for psoriasis on your feet

Moisturize twice a day, especially after washing. At night, apply a thick layer and wear cotton socks.
Soften scale gently. A short, lukewarm soak of about 10 minutes before moisturizing can help. Skip soaks if you have diabetes, numb feet or poor circulation.
Don’t pick or peel scale, and don’t cut at cracks or thick skin yourself.
Reduce friction. Wear well-fitting, cushioned shoes and soft, seamless socks, since rubbing can set off new patches.
Check your feet every day for cracks, redness or signs of infection.
Look after your overall health. Stopping smoking, drinking less alcohol, managing stress and losing excess weight can all ease psoriasis for many people.

When to see a doctor

Go to the emergency room if you suddenly develop widespread pus-filled bumps or red, peeling skin over much of your body, especially with fever or chills. These are rare, serious forms of psoriasis.

Get seen promptly if:

cracks are deep, bleeding or look infected: spreading redness, warmth, swelling or pus
you have diabetes, neuropathy or poor circulation and have cracked or broken skin on your feet
a toe or heel becomes swollen and painful

Book a visit if:

a scaly rash on your feet hasn’t cleared after 2 weeks of over-the-counter treatment
pain or cracking makes walking or standing hard
your toenails are thick, pitted or lifting
your treatment isn’t working as well as it used to

Psoriasis care is often shared. A dermatologist manages the skin and prescription medicines, a rheumatologist treats psoriatic arthritis, and a podiatrist looks after the feet themselves: cracks, thick skin, nails, shoes and foot pain. If your feet are what’s holding you back, you can find a podiatrist near you and book online.

Questions, answered

It usually looks like thick, dry patches with clear edges and silvery-white scale, most often on the soles and heels. The patches can be red or pink on lighter skin and purple, brown or gray on darker skin, and they often crack. Some people have small yellow-white pus bumps on the soles instead, and toenails may be pitted, thick or lifting.
