Itchy feet can become the bane of any day: you’re either driven mad trying to resist the urge to scratch; or by the redness, swelling, cracking, and flaking as a result of uncontrollable itching. While the cause could be something benign such as dry skin or excessive sweating, it could also indicate an infection or undiagnosed skin condition. Moreover, if left untreated, other complications could arise, such as a secondary infection.

The itching and burning will only continue to plague you until you accurately identify the source and treat it accordingly. Besides the obvious bug bites or allergic irritation, itchy feet are most commonly caused by a fungal infection or an underlying skin condition. In rare cases, itching could also suggest the presence of another medical condition, such as diabetes. Only examination from a trusted podiatrist can accurately diagnose your foot condition.

Here’s a look at the possible causes of itchy feet, treatment, and prevention tips to keep your feet feeling fresh.

Fungal Infection

When itchy feet are the main symptom, fungal infection is usually the primary suspect: specifically, tinea pedis, or athlete’s foot. Constant exposure to sweat and bacteria, in addition to walking barefoot on contaminated surfaces, make your feet the ideal breeding ground for fungal infection.

Athlete’s foot is an extremely contagious fungal infection which is easily spread through contact with infected surfaces, usually in damp spaces such as showers and gym locker rooms. In fact, it can even be spread through shared towels or linens. The first sign of infection is a dry, scaly rash that causes unbearable itching on the bottoms of the feet and between the toes. While the symptoms can be abated by certain over-the-counter creams, only a podiatrist can effectively cure you of the infection. Once cured, vigilant prevention should be practiced to avoid re-infection.

Skin Conditions

A number of skin conditions can lead to insatiable itching of the feet.

Eczema: Eczema can affect most parts of the body, but dyshidrotic eczema specifically affects the feet and hands. It is characterized by tiny itchy blisters formed on the soles of the feet, which then dry and cause cracking on the skin. If not properly cared for, the exposed skin can become vulnerable to infection. Since dyshidrotic eczema can share symptoms with other skin conditions, a skin sample will likely be taken for proper diagnosis.

Contact dermatitis: Contact dermatitis is a skin irritation that results from contact with an allergen or irritant, which appears similar to a rash. Allergic contact dermatitis is caused by skin exposure to an allergen, triggering an allergic reaction in the affected area. Irritant contact dermatitis is distinct in that it does not involve the immune system, but is instead the result of skin damage caused by exposure to an irritant that rids your skin of its protective surface oils. Common triggers of contact dermatitis include poison ivy, latex, nickel, chemical fragrances, topical medications, and leather.

Psoriasis: Psoriasis is an autoimmune disorder which causes rapid skin cell turnover, resulting in incredibly itchy and scaly dry patches called plaques. The plaques are the result of layers of new skin cells rising so quickly that the dead skin piles atop the surface, rather than gradually sloughing off, form dry patches of thickened skin. Plaques are commonly found on the bottoms of the feet, as well as the elbows and knees.

Additional Sources of Itchy Feet

Here are a few potential, albeit less likely, perpetrators of itchy feet:

• Diabetes: Skin conditions can sometimes indicate diabetes. A condition called eruptive xanthomatosis produces small itchy bumps on the skin as a result of severe diabetes. The condition subsides once the diabetes is managed and under control.
• Scabies: Scabies is an infection of the human itch mite which burrows just below the skin to lay its eggs. The infestation causes intense itching which worsens at night, a pimply rash, and tiny blisters. You can also see traces of the burrows on the skin, which appear as thin whitish lines along the surface. Scabies is easily spread, and should receive medical attention to stem the infection right away.
• Pitted Keratolysis: Pitted keratolysis is a non-contagious bacterial infection, caused by wearing damp, restrictive footwear. It produces shallow pits beneath the toes and soles of the feet, accompanied by itching, burning, and an extremely foul odor.

Prevention Tips

The feet are constantly plagued by bacteria, and need to be cleaned just like your hands. To keep your feet comfortable and fresh, follow these basic hygiene tips:

• Avoid walking barefoot anywhere, especially on damp communal surfaces.
• Always wear dry, clean socks and shoes made of breathable materials.
• Wash your feet thoroughly, and do your best to keep them dry.
• If someone you know has an infection, do not share towels or linens, and protect your feet from contaminated surfaces.
• Keep your toenails trimmed and clean.

If you suspect an infection is already present, schedule an examination with a reputable podiatrist right away.

What is Athlete’s Foot?

Athlete’s foot is a fungal infection caused by the tinea fungus, and is usually found between the toes. Its medical name is tinea pedis– ringworm of the feet. It most commonly affects those who are highly active, and thus prone to having sweaty feet confined within tight shoes often and for extended periods of time.

Athlete’s foot is not only embarrassing, but highly contagious. The infection can spread via contaminated surfaces such as floors and laundry. If not careful, the infection can also spread to other parts of the body, such as the hands, nails, and groin.

Learn more about the symptoms of athlete’s foot, and how to prevent an infection of your own.

Athlete’s Foot Symptoms

The visual indication of an athlete’s foot infection is a red rash between the toes that is scaly in appearance, with some occurrences even presenting blisters or ulcers. This rash causes the sensations of itching, stinging, and burning. The itching is usually most intense immediately after removing the socks and shoes.

You may also experience dry, cracked, raw, or peeling skin between the toes and on the soles of the feet. Thick, discolored toenails detached from the nail bed are another indication of an infection.

Some strains of the tinea pedis fungus can cause chronic dryness and chafing on the soles and sides of the feet. This can often be mistaken for other skin conditions such as eczema. The infection can spread to other parts of the body, such as your hands, if you pick at the infected sites.

Causes & Risk Factors

Athlete’s foot is closely related to ringworm and jock itch, and is actually caused by the same fungal infection. The tinea pedis fungus thrives in warm, damp environments, making sweaty socks the perfect incubator for its growth. It is most commonly found in moist public spaces, such as communal locker rooms, public showers, gyms, and swimming pools. Walking anywhere barefoot is highly discouraged.

Certain environmental factors put you at higher risk of contracting an athlete’s foot infection. For one, males are more likely to develop the infection. If you are highly active, meaning that you wear sweaty socks for extended periods of time, then you are at higher risk. Since the fungus is highly contagious, being exposed to an environment such as a communal gym or shower with an infected individual makes you extremely likely to catch the infection. Moreover, if you share a home with someone who is infected, you may catch the infection through contaminated floors, shared bedding, shared towels, etc. For this reason, those who tend to walk barefoot in public spaces are at a higher risk. This includes those with compromised immune systems, such as those with diabetes.

Athlete’s Foot Diagnosis

An experienced podiatrist can often diagnose an athlete’s foot infection through visual confirmation. However, he or she may also take skin samples to view under a microscope or send to a lab for testing for a definitive diagnosis.

Common tests include:

• PAS stain
• Skin culture
• Skin biopsy

Athlete’s Foot Treatment

Athlete’s foot is similar to other common fungal infections, and mild cases can be treated with over-the-counter antifungal medications such as creams and ointments. Over-the-counter antifungal medications include: Lamisil AT and Lotrimin AF.More serious cases may require prescription medication to be applied topically to the feet. For the most severe cases, your doctor may prescribe oral antifungal pills to flush out the infection. Common oral antifungal prescriptions include: Sporanox, Diflucan, Gris-Peg or Lamisil.

At home, you may soak your feet in salt water to help remedy the blistering. Tea tree oil is also a common natural remedy used with some limited success. Of course, only a doctor’s visit can be trusted to completely eliminate the infection.

Prevention

The most effective treatment for any infection is prevention.

• Avoid walking barefoot in any public space, especially ones that are humid and moist such as a locker room.
• If you know that a family member has contracted the infection, do not walk barefoot on any communal floors, and refrain from sharing linens such as bedding and towels. Even try to use different showers until the infection clears, if possible.
• Wash your feet thoroughly with antibacterial soap, and dry them fully.
• Apply antifungal powders daily, if necessary.
• Wear socks with breathable fibers such as cotton or wool, or specially designed moisture-wicking features.
• Change your socks as often as possible, and alternate between different pairs of shoes to allow them to dry out between uses.
• If the infection seems unavoidable due to a highly active lifestyle, seek treatment at the first signs of infection to avoid it from spreading to the hands, nails, or groin.
• Seek medical attention immediately if you have diabetes or compromised immune health.

Potential Complications

The fungal infection can potentially spread to your hand, your nails, and your groin (jock itch).

You may also develop an allergic reaction to the fungus, resulting in blistering on the affected area. Moreover, an additional bacterial infection may develop. A bacterial infection may also be present if your foot becomes painful and swollen, or if it develops pus and drainage. Seek medical attention if you develop a fever to prevent the infection from spreading throughout the body.
