Athlete's foot

A few months ago, I started developing small blisters between my toes (on both feet).
Later, the sides of my feet and the soles began to develop blisters as well (the areas with blisters are very itchy).
After a while, the skin becomes hard and slightly darker than the surrounding areas, and then it keeps peeling off.
Could this be athlete's foot? I understand that there are several types of athlete's foot, right? If this is considered athlete's foot, which type would it be? Do you see patients with this symptom in your clinic?

Hello: Regarding the mentioned interdigitating blisters, athlete's foot is a possibility; however, if small blisters also occur on the sides of the soles and there is post-healing pigmentation increase and thickening, it is more likely to be dyshidrotic eczema.
The hot and humid weather in Taiwan makes this a common skin condition.
It is essential to consult a dermatologist for proper diagnosis and avoid applying random medications, as this may lead to allergic reactions and acute changes with severe inflammation.
Wishing you safety and health.
Sincerely, Dr.

More Info

Athlete's foot, medically known as tinea pedis, is a fungal infection that commonly affects the skin of the feet, particularly between the toes and on the soles. It is characterized by various symptoms, including itching, burning, and the formation of blisters or sores. Based on your description of small blisters forming between your toes and on the sides of your feet, along with the itching and subsequent hardening and darkening of the skin, it is quite possible that you are experiencing a case of athlete's foot.

Athlete's foot can be classified into several types, primarily based on the location of the infection and the symptoms presented:
1. Interdigital Tinea Pedis: This is the most common form, occurring between the toes. It often presents with itching, burning, and peeling skin, and can lead to the formation of blisters.

2. Moccasin Tinea Pedis: This type affects the soles of the feet and the sides, leading to dry, scaly skin that may become thickened and discolored. It can sometimes extend to the toenails.

3. Vesicular Tinea Pedis: This form is characterized by the presence of vesicles or blisters, often on the instep or the sides of the feet. These blisters can be itchy and may burst, leading to crusting.

4. Ulcerative Tinea Pedis: This is a less common but more severe form that can occur in individuals with weakened immune systems or those who have other skin conditions. It presents with painful ulcers and can lead to secondary bacterial infections.

Given your symptoms, it seems that you may be experiencing either the vesicular or interdigital type of athlete's foot. The presence of blisters and the subsequent hardening of the skin are indicative of a fungal infection that requires appropriate treatment.

Treatment Options
1. Topical Antifungals: Over-the-counter antifungal creams, powders, or sprays (such as clotrimazole, miconazole, or terbinafine) can be effective in treating athlete's foot. These should be applied as directed, usually for at least two weeks, even if symptoms improve sooner.

2. Oral Antifungals: In more severe cases or if topical treatments fail, a healthcare provider may prescribe oral antifungal medications.

3. Proper Foot Hygiene: Keeping your feet clean and dry is crucial. Make sure to wash your feet daily, dry them thoroughly (especially between the toes), and change socks regularly.

4. Footwear Choices: Wear breathable shoes and moisture-wicking socks to reduce the risk of fungal growth. Avoid walking barefoot in communal areas like pools or locker rooms.

5. Avoiding Irritants: If you have sensitive skin, avoid using harsh soaps or lotions that may irritate the affected areas.

6. Consulting a Specialist: If your symptoms persist or worsen despite treatment, it is advisable to consult a dermatologist or a podiatrist. They can provide a definitive diagnosis and may perform a skin scraping to confirm the presence of a fungal infection.

In conclusion, based on your symptoms, it is likely that you are experiencing a form of athlete's foot. Identifying the specific type can help tailor the treatment approach. It is essential to address this condition promptly to prevent further complications and to alleviate discomfort. If you have access to a clinic or a specialist, it would be beneficial to seek a professional evaluation to confirm the diagnosis and receive appropriate treatment.
