White rice-sized growth on the sole of the foot

The growth of white rice-sized bumps on the soles of feet is mainly caused by two reasons: athlete's foot and tinea pedis. Athlete's foot is also known as a fungal skin infection. Small white pimples will grow on the soles of the feet, and the skin between the toes will also peel and become red and swollen. It is more common in the summer. Then there is tinea pedis, which is also caused by fungi. Small blisters grow on the soles of the feet, gradually turn into large bullae, and then ulcerate.

It is considered to be athlete's foot, which is a very common fungal infection of the skin. 70-80% of adults have athlete's foot, but the severity varies. It often gets worse in summer and gets better in winter, but some people never get better all year round. Also known as "athlete's foot". Tinea pedis is a dermatophyte infection of the soles of the feet and between the toes, which can extend to the heels and dorsum of the feet, but those occurring on the dorsum of the feet are tinea corporis. Trichophyton rubrum is the main pathogen of tinea pedis. You can use Zuguangsan to soak the feet in hot water, and the medication is usually used once every five to seven days. Use it according to the instructions, pay attention to personal foot hygiene, and do not wash slippers in an unsterilized basin with people with athlete's foot.

Tinea pedis (commonly known as "athlete's foot" or athlete's foot) is caused by fungal infection. The skin damage often occurs unilaterally (i.e. one foot) first, and then infects the other side after several weeks or months. Blisters mainly appear on the soles and sides of the toes, most commonly between the third and fourth toes, and can also appear on the soles of the feet. They are deep small blisters that can gradually merge into large blisters. A characteristic of the skin lesions of tinea pedis is that they have clear boundaries and can gradually expand outward. As the disease progresses or scratching occurs, erosion, exudation, or even bacterial infection and pustules may occur.

Ringworm is a contagious skin disease of the feet caused by pathogenic fungi. Tinea pedis is prevalent throughout the world and is more common in tropical and subtropical regions. In our country, the incidence of tinea pedis is also quite high. There are no sebaceous glands on the soles of the feet and between the toes, and thus a lack of fatty acids that inhibit skin filamentous fungi, and the physiological defense function is poor. However, the skin in these areas is rich in sweat glands and sweats more frequently. In addition, the air circulation is poor and the local area is humid and warm, which is conducive to the growth of filamentous fungi. In addition, the stratum corneum of the skin on the soles of the feet is thicker, and the keratin in the stratum corneum is a rich nutrient for fungi, which is conducive to the growth of fungi.

During pregnancy, women's endocrine changes cause their skin's ability to resist fungal infections to decrease, making them more susceptible to tinea pedis. Obese people are more likely to suffer from tinea pedis due to moisture between the toes and sweat. Trauma to the foot skin destroys the skin's defense function and is also one of the factors that induce tinea pedis. Diabetic patients are also susceptible to tinea pedis because of the disorder of substance metabolism caused by lack of insulin and the increased sugar content in the skin leading to decreased resistance. Abuse of antibiotics, long-term use of corticosteroids and immunosuppressants, etc., which can cause imbalance in the normal skin flora, can also increase susceptibility to tinea pedis.

The incidence of tinea pedis is also related to lifestyle habits. Some people do not pay attention to foot hygiene and the condition of their shoes and socks, providing a good breeding ground for fungi.
