Peeling feet do not itch or smell, just peeling skin

Tinea pedis 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. The clinical manifestations are blisters, peeling, or pale and soft skin between the toes. Erosion or thickening, roughness, and cracking of the skin may also occur, and may spread to the soles and edges of the feet, causing severe itching. It may be accompanied by local suppuration, redness, swelling, pain, inguinal lymph node enlargement, and even secondary infections such as calf erysipelas and cellulitis. Due to scratching the itchy area with the hands, it is often transmitted to the hands and causes tinea manuum (tinea pedis). When fungi grow on the nails, it becomes onychomycosis (onychomycosis). Fungi love moist and warm environments. The hot summer weather and sweating, as well as people wearing rubber shoes and nylon socks, provide a breeding ground for fungi. The condition usually improves in the winter, manifested by cracking of the skin. There are several types: 1. The blister type mostly occurs in summer, characterized by the appearance of rice-sized, deep blisters between the toes, on the edges of the feet, and on the soles of the feet, which are scattered or distributed in groups. The blister walls are thick, the contents are clear, and they are not easy to rupture. They fuse together to form multi-chamber blisters. When the blister walls are torn off, a honeycomb base and bright red erosive surface can be seen, which causes severe itching. 2. The erosive type is characterized by the softening and whitening of the local epidermal stratum corneum. Due to constant friction when walking, the epidermis falls off, revealing a bright red eroded surface; in severe cases, the skin between the toes and the junction of the toes and the soles of the feet can be affected, with severe itching, mostly between the 3rd, 4th, and 5th toes. Common in people with excessive sweating. 3. The symptoms of the scaly and keratotic type are thickening, roughness, and scaling of the skin on the soles, edges of the feet, heels, and toes. The scales are in the form of flakes or small dots and fall off repeatedly. Prevention 1. Pay attention to cleanliness, keep skin dry, keep feet clean, wash several times a day, and change socks frequently. 2. Foot basins and foot towels should be used separately to avoid infecting others. 3. It is not advisable to wear non-breathable shoes such as sports shoes and hiking shoes to avoid excessive foot sweating and aggravated foot odor. People with tight spaces between toes can use clean gauze or cotton balls to sandwich the toes or choose split-toe socks to facilitate moisture absorption and ventilation. 4. Do not eat foods that can easily cause sweating, such as hot peppers, raw onions, raw garlic, etc. 5. The mood should be calm. Excitement and agitation can easily induce sweating and aggravate tinea pedis. 6. Tinea pedis is a contagious skin disease. You should avoid scratching to prevent self-infection and secondary infection. |
