Foot rash: Causes, symptoms, and treatments

A foot rash can occur due to an allergic reaction or infection. Most foot rashes, such as athlete’s foot and contact dermatitis, are treatable with over-the-counter (OTC) medications.

However, other types of foot rashes, such as cellulitis may require medical intervention.

In this article, we list a few common causes of foot rashes along with their symptoms and treatment options.

Tinea pedis, more commonly known as athlete’s foot, is a highly contagious fungal infection that develops on the feet.

A fungus called Trichophyton causes athlete’s foot. This fungus thrives in warm, moist environments, such as shower floors and the inside of shoes.

Athlete’s foot often leads to itchy, burning skin between the toes. Other symptoms of the condition include:

• dry, scaly, or cracked skin
• flushed or raw skin
• weak, discolored toenails
• cracked or oozing blisters on the feet

Treatment

Most people can treat athlete’s foot with an OTC antifungal treatment, usually in the form of an oral tablet or a liquid or cream. More severe infections may require prescription-strength medication.

Topical steroids, such as hydrocortisone, can help reduce inflammation and relieve itching and soreness.

Contact dermatitis is a rash that occurs when a substance irritates the skin or produces an allergic reaction.

Substances that may cause contact dermatitis can include:

• metals, such as nickel
• makeup
• latex
• frequent washing or contact with water
• bleach

Treatment

People can avoid the substance that they think is causing contact dermatitis to see whether their rash clears within 1–3 weeks. Antihistamines and topical corticosteroids may help relieve symptoms.

Poison ivy, oak, and sumac grow in both wooded and marshy areas. These plants produce sap that contains an allergen called urushiol.

Urushiol can trigger an allergic skin reaction called contact dermatitis. About 50–75% of adults in the United States are allergic to urushiol.

Symptoms of a poison ivy, oak, or sumac rash include:

• flushed, itchy skin
• bumps or blisters on the skin
• swollen, tender skin
• difficulty breathing
• fever

Treatment

Poison ivy, oak, and sumac rashes usually clear up by themselves within a few weeks.

If someone believes that they have had exposure to urushiol, they can remove the oils immediately by washing themselves and their clothes with soap and water.

OTC topical treatments, such as calamine lotion and hydrocortisone, can help relieve itching and swelling. A doctor may prescribe an oral antihistamine to lessen the allergic reaction.

Dyshidrotic eczema, or dyshidrosis, is a common form of eczema that causes itchy blisters on the palms of the hands and soles of the feet.

According to the National Eczema Association, dyshidrotic eczema is twice as common in females as males.

Symptoms can include:

• deep blisters on the toes, palms, edges of the fingers, and soles of the feet
• flushed, itchy skin
• scaly, cracked, or flaking skin
• swollen, tender skin

Treatment

There is currently no cure for dyshidrotic eczema. Treatments for this skin condition involve reducing symptoms and preventing secondary infections and other complications.

A doctor may prescribe a topical steroid to reduce swelling and itching. Botox injections can lessen sweating and excess moisture in the hands and feet, which can prevent infections.

At-home treatments for dyshidrotic eczema include:

• soaking the hands and feet in cool water
• applying a cold compress to the affected skin
• using moisturizer or cream that repairs the skin barrier

Hand, foot, and mouth disease (HFMD) is a skin condition that occurs due to coxsackievirus and enterovirus infections. HFMD is highly contagious, and people can contract it by:

• touching a person with the infection
• touching objects or surfaces that carry the virus
• breathing air that contains the virus particles

Although HFMD is most common among young children under the age of 5, anyone can develop the infection.

HFMD usually leads to small spots appearing on the hands and feet, as well as mouth sores. Other symptoms include:

• painful blisters
• fever
• sore throat
• loss of appetite
• pain when eating or swallowing

Treatment

There are no specific treatments for HFMD. People may be able to manage symptoms with OTC medication that reduces fever and pain.

Drinking cold liquids can help keep people hydrated while soothing a sore throat.

According to the Centers for Disease Control and Prevention (CDC), most people with HFMD get better within 7–10 days.

Cellulitis is a bacterial infection that develops in the deep layers of the skin and on the lower legs and feet. Symptoms include:

• skin that appears swollen
• skin that feels warm, tender, or painful to the touch
• skin dimpling
• blisters
• fatigue
• fever or chills
• cold sweats
• nausea or vomiting
• swollen, tender lymph nodes

People with light skin tones may also notice reddened skin in the affected area.

Treatment

Cellulitis can develop suddenly and can be life threatening without treatment.

Doctors usually prescribe antibiotics to treat the bacterial infection responsible for cellulitis. Other beneficial at-home treatment options include:

• keeping the affected leg or foot raised to reduce swelling
• taking OTC pain medications to relieve pain and reduce fever
• avoiding scratching or itching the affected skin
• keeping the area clean and dry

Scabies is a skin condition that occurs when microscopic scabies mites burrow into the upper layer of the skin. These mites then feed on skin cells and lay eggs. Symptoms of scabies usually develop within 4–8 weeks.

A scabies infestation can lead to a skin rash and intense itching. The affected area of skin may develop pimple-like blisters or thick, crusty scales.

Treatment

People cannot treat scabies with at-home remedies. A doctor must prescribe topical medications that kill scabies mites.

After starting treatment, people will need to disinfect their bedding, clothing, and any other fabrics that they regularly use. Doing this will help prevent recurring infestations.

People should contact their healthcare provider if their foot rash is painful or significantly interferes with their daily activities.

Parents and caregivers should see a healthcare provider if a child or infant develops a skin rash or blisters.

It is important for a person to seek medical attention straight away if their rash does not improve with treatment or they develop a fever.

There are numerous possible causes of foot rashes, ranging from allergic reactions to infections. Most cases clear up on their own, but OTC medications can help relieve swelling, itching, and pain during recovery.

A person should speak with a doctor if they have a foot rash that does not respond to treatment or they develop signs of an infection.

Fungus on the feet – prevention and effective treatment

Epidermophytosis of the feet is a group of fungal diseases that have a common localization and similar clinical manifestations. Very common and affect people of any age (rarely children) prone to chronic relapsing course.

Infection occurs in baths, showers, on beaches, gyms, when using someone else’s shoes and other household items contaminated with fungal elements.

In the pathogenesis of the disease, the anatomical and physiological features of the skin of the feet, increased sweating, changes in the chemistry of sweat, metabolic and endocrine abnormalities, injuries of the lower extremities, and vegetative dystonia are of great importance. Pathogens can be in a saprophytic state for a long time without causing active clinical manifestations. Athlete’s foot has several clinical forms, each of which can be combined with nail lesions.

Symptoms and course

The process most often begins in the interdigital spaces, mainly between the most closely adjacent 4th and 5th fingers. When you feel a slight itch at the bottom of the interdigital fold, a strip of swollen and slightly flaky epidermis appears. After 2-3 days, a small crack appears here, releasing a small amount of serous fluid. Sometimes the stratum corneum falls off, exposing a pink-red surface. The disease, gradually progressing, can spread to all interdigital folds, the plantar surface of the fingers and adjacent parts of the foot itself. The serous fluid seeping to the surface serves as an excellent nutrient material for the further reproduction of fungi.

When fungi enter through the disturbed stratum corneum into the deeper parts of the epidermis, the process is complicated by an eczematous reaction. Numerous, strongly itchy, clear fluid-filled blisters appear, which merge and erode in places, leaving weeping areas.

The process can move to the back surface of the foot and fingers, the sole, capturing its arch to the very heel. The disease, then weakening, then again intensifying, without proper treatment and care, can drag on for many years. Often, this is accompanied by a complication of a secondary pyogenic infection: the transparent contents of the vesicles become purulent, the inflammatory redness intensifies and spreads beyond the boundaries of the lesion, the foot becomes edematous, the patient’s movements are difficult or impossible due to severe pain; subsequent complications may develop in the form of lymphangitis, lymphadenitis, erysipelas, etc.

In some cases, epidermophytosis on the soles is expressed by the appearance on the initially unchanged skin of separate groups of itchy, deeply located, dense to the touch blisters and blisters with transparent or slightly cloudy contents. After their spontaneous opening, the cover of the bubbles disappears, remaining in the form of a corolla only along the edges of the lesion; the central parts have a smooth, pink-red color, slightly flaky, less often – a weeping surface; often new bubbles appear on it. Due to their merger, the lesion expands and can capture significant areas of the soles.

The absorption of allergens (fungi and their toxins) is a sensitizing factor for the whole organism, increases the sensitivity of the skin, and an allergic rash may appear on it. It is more often observed on the hands (palms). Sharply limited erythematous discs are formed, dotted with a large number of small bubbles with transparent contents, which burst, exposing an erosive, weeping surface surrounded by a widening rim of swollen and exfoliating epidermis. Fungi are not usually found in these lesions.

Epidermophytosis of the feet begins mainly in the summer. Increased sweating, insufficient drying of the interdigital spaces after bathing contribute to the introduction of the fungus.

The defeat of the nails with mycosis of the feet is observed mainly on the 1st and 5th fingers, usually starting from the free edge. The nail is thickened, has a yellowish color and a jagged edge. Gradually, more or less pronounced subungual hyperkeratosis develops.

Treatment

Particular attention should be paid to the careful processing of lesions.

The patient should take daily warm foot baths with potassium permanganate. In this case, it is necessary to remove the crusts, open the blisters, cut off the fringe along the edges of the erosion, as well as the covers of festering blisters. After the bath, wet-drying dressings or lotions are applied with an aqueous solution of copper sulfate (0.1%) and zinc (0. 4%) or with a 1% aqueous solution of resorcinol. After wetting stops, dermozolon, mycosolone, and then alcoholic fungicidal solutions, Castellani paint, and, finally, if necessary, fungicidal pastes and ointments, are applied.

The effectiveness of treatment depends not so much on the choice of a pharmacological drug, but on their correct, consistent use in accordance with the nature of the inflammatory reaction.

Fungicidal treatment is carried out until the test results for fungi are negative.

Extremely important is the anti-relapse treatment carried out within a month after the elimination of the lesions – wiping the skin of the feet with 2% salicylic or 1% thymol alcohol and dusting with 10% boric powder. For the same purpose, it is necessary to thoroughly wipe the inner surface of the shoe with a formaldehyde solution, wrap it for 2 days in an airtight fabric, then ventilate and dry, and socks and stockings for 10 minutes. boil.

With the complication of athlete’s foot with pyococcal infection, antibiotics are prescribed – methicillin, cephaloridine, oleandomycin, metacycline, erythromycin.
