Athletes Foot
Athletes Foot is a fungal infection that typically occurs on the feet. Because the infection is common among people who exercise or play sports, it was named Athletes Foot. However, anyone can experience Athletes Foot.
Causes
Fungus thrives in warm, dark, moist places, such as the inside of a shoe, in locker rooms and showers, and around swimming pools. When you walk through a contaminated area, like a swimming pool locker room, your bare feet come in contact with the fungus. If your feet or the area between your toes stays moist, the fungus will grow.
Risk Factors
A risk factor is something that increases your chance of getting a disease or
condition.
- Prior Athletes Foot infection
- Walking barefoot in locker rooms or public places
- Not keeping your feet clean and dry
- Wearing air-tight or poorly ventilated shoes or boots
- Sweaty feet
- Hot, humid weather
- Disorders of the immune system
Symptoms
Athletes Foot symptoms usually start between the toes and often occur
in combination. As the infection progresses, it may spread to the soles or
arches of the feet or to the toenails.
Symptoms include:
Symptoms include:
- Dry skin
- Itching, which worsens as the infection spreads
- Scaling
- Cracking
- Redness
- A white, wet surface
- Blisters, which may open and become painful
Diagnosis
The doctor will ask about your symptoms and medical history, and perform a physical exam. The doctor may scrape a small sample off the infected skin for testing. Infections caused by bacteria, rather than a fungus, may cause similar symptoms. Other conditions may also mimic Athletes Foot. Getting an accurate diagnosis is important for successful treatment.
Treatment
Treatment aims to rid the body of the infection. Therapy may include good
foot hygiene or medication. Many over-the-counter antifungal medications are
available. However, if the infection persists for two weeks or more, seek
medical care.
Foot Hygiene
You may need a prescription medication, because an over-the-counter product may not be effective in fighting the fungus. The doctor may prescribe an antifungal medication to be taken by mouth or applied to the feet. It is important to continue taking any prescribed medication for the entire time instructed by the doctor. Do not stop any medication without the doctor's approval, even if the infected areas look better. Treatment generally lasts 4-8 weeks. Shortening the treatment plan often results in another infection. Wash your hands after applying topical medications.
Topical medications include:
Foot Hygiene
- Gently wash your feet often and completely dry all areas, including between the toes.
- Put a dusting of antifungal foot powder on your feet to absorb moisture.
- Change your shoes and socks frequently.
- Do not swim or use public locker rooms when you have an infection. This will help prevent spreading the infection to other people.
