Caused by various fungi, tinea pedis, commonly known as athlete’s foot, is a common fungal infection affecting the skin of the feet. In the warm environment caused by wearing snug shoes for prolonged periods, the most common areas for the infection are between the toes, but it can spread to or also appear on the soles, sides, or tops of the feet, and can even appear under the toenails. Highly contagious due to being a fungal infection, athlete’s foot causes irritation to the affected areas, often described as burning or stinging while causing flaking skin, peeling, and redness occasionally alongside a foul smell. Left untreated, an athlete’s foot nail infection and other parts of the body like the hands. Fortunately, athlete’s foot fungus treatment and medications are highly effective, with the vast majority of cases clearing within two weeks.
Athlete’s foot symptoms can vary, with some cases featuring no noticeable signs at first and others being irritating enough to be a problem. In either case, the most common symptoms of athlete’s foot include:
Itching: Persistent and intense itching is a hallmark of athlete's foot. It can be particularly bothersome, leading to discomfort.
Redness: The affected skin often becomes red, especially between the toes and on the sides of the feet.
Peeling or Scaling: The skin may peel or flake, and there may be visible scaling on the surface.
Burning Sensation: Some individuals may experience a burning or stinging sensation on the affected areas.
Cracking or Fissures: The skin may develop small cracks, especially in areas that are prone to friction or moisture.
Athlete’s Foot Blisters: Fluid-filled blisters may form, contributing to the overall discomfort.
Dry Skin: Athlete's foot can cause dryness on the affected areas of the feet.
Foul Odor: Fungal infections can sometimes lead to an unpleasant odor, particularly if the infection involves the toenails.
Athlete's foot is primarily caused by fungal infections, most commonly due to dermatophytes such as Trichophyton. These fungi thrive in warm, moist environments, making the spaces between the toes an ideal breeding ground. The infection is highly contagious and can be contracted through direct contact with an infected person or by coming into contact with contaminated surfaces, such as floors in public showers, swimming pools, shared towels, or shoes. Additionally, wearing tight, closed-toe shoes for prolonged periods, excessive sweating, and not keeping the feet clean and dry can create conditions favorable for fungal growth, increasing the risk of developing athlete's foot.
An athlete’s foot diagnosis is most often a clinical examination by a medical professional, with some cases needing laboratory tests to rule out causes with similar symptoms. Dermatologists and doctors alike typically recognize the characteristic signs and symptoms of athlete's foot during the first round of examinations. In the event that a test is needed, the most common include:
Skin Scraping: The healthcare provider may gently scrape off a small sample of the affected skin for microscopic examination.
Culture: A fungal culture involves placing the collected skin sample in a special medium to encourage fungal growth.
Wood’s Lamp Examination: In some instances, a Wood's lamp (a specialized ultraviolet light) may be used to examine the affected skin. Certain types of fungi may fluoresce under this light.
Athlete’s foot fungus treatment typically involves topical antibiotics or medications that directly combat the infection and clear it within a reasonable amount of time. Most often, this is in the form of creams, lotions, or powders containing active ingredients like clotrimazole, miconazole, terbinafine, or tolnaftate. Alongside treatment, good foot hygiene is key, with keeping your feet clean and dry being the primary focus.
Alongside athlete’s foot fungus treatment, management of the condition primarily involves keeping the affected foot clean and dry while making efforts to prevent spread. This means washing your feet each time you bathe and after you work out to remove any chance for an environment conducive to fungal growth from developing. Wearing breathable footwear, regular foot inspections, and using disinfectant on your go-to pair of shoes when possible.
Preventing athlete's foot involves adopting good foot hygiene practices and taking precautions to reduce the risk of fungal infections. Here are some tips to help prevent athlete's foot:
Keep Feet Clean and Dry
Change Socks Regularly
Choose Breathable Footwear
Apply Antifungal Powder to your feet and inside your shoes
Avoid Walking Barefoot in Public Areas
Rotate Shoes Worn Regularly
Keep Toenails Trimmed
Limit Moisture when wearing shoes
Regularly Disinfect Shoes
Avoid Sharing Personal Items
Includes but not limited to:
Topical antifungal medications (Ketoconazole, Ciclopirox, or Naftifine)
Oral antifungal therapy (Terbinafine)

"I can’t believe I did not know about this kind of service! This was absolutely perfect for my health concern and they were able to provide me with the necessary medication and with such cinch. Completely recommended this service. For minor health concerns, this can save you an unnecessary and costly trip to an urgent care center."
"Amazing!! Easy and fast! I didn’t have to take my 4 year old into an urgent care where only god knows what germs are there. The doctor sent the script right to my pharmacy within minutes!!!"
"I would give 10 stars if I could! CallonDoc is literally the reason I am recovering instead of suffering as I write this. I was skeptical at first, but I’m not kidding when I tell you I got prescribed my antibiotics and picked it up at the pharmacy within 2 hours. So instead of waiting & paying around 300$...I paid 40$!! I’m very pleased."
Athlete's foot is unlikely to resolve on its own and often requires antifungal treatment to effectively eliminate the infection. Without proper intervention, the condition may persist or worsen over time.
Athlete's foot and jock itch are both fungal infections caused by dermatophytes, but they affect different areas of the body. Athlete's foot primarily targets the feet, while jock itch occurs in the groin and thigh areas, and each typically requires specific treatments.
Yes, athlete's foot is contagious and can spread through direct contact with infected skin or by contact with contaminated surfaces such as floors, towels, or shoes. Taking precautions, such as practicing good hygiene and avoiding
