Why are my feet and floors itchy?

Disease is a very common situation in people's daily lives, because many factors in people's daily lives can cause the occurrence of diseases, but many people do not know what disease they have when they have some signs of disease. Many people do not know what disease itching on their feet is a symptom of. So, what causes itchy feet?

First, why are your feet and floors itchy? Tinea pedis (commonly known as "Hong Kong foot" or athlete's foot) is caused by fungal infection. The skin damage often occurs on one side (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. 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.

Second, 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 causes onychomycosis (onychomycosis). Fungi like 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.

Why do my feet and floors itch? Do not use strong irritating medicines externally. It is best to let the wound surface dry and then apply the medicine. You can apply a 1:8000 potassium permanganate solution as a wet compress, then apply external oil or powder, and after the skin is dry, switch to creams or ointments such as terbinafine hydrochloride. 2. If the skin is severely keratinized and thickened, antifungal drugs are difficult to penetrate and absorb. You can first use 10% salicylic acid ointment or compound benzoic acid ointment to soften the cuticle, and then use antifungal drugs. If the skin is obviously dry and cracked, you can soak it in warm water each time to soften the cuticle, and then use antifungal drugs. For those with obvious dry and cracked skin, you can apply ointment locally after soaking in warm water each time, then seal it with plastic film and wrap it with a bandage. Remove it after 24 to 48 hours and then use antifungal drugs. 3. If small blisters appear on the feet but have not broken, you can first soak them in 3% boric acid solution, and then use antifungal creams such as bifonazole cream. 4. For tinea pedis complicated with bacterial infection, in principle, local anti-bacterial treatment should be used first. Furazolidone solution or 1:2000 berberine solution can be used for wet compresses. For severe infection, oral antibiotics can be used, such as cephalexin capsules, erythromycin, etc. 5. Systemic treatment For stubborn tinea pedis, oral medications can be given if there are no contraindications. Such as terbinafine, itraconazole, fluconazole, etc. These oral medications are effective, but attention should be paid to their possible side effects and they should not be used by people with poor liver function. 6. Adhere to the medication. Tinea pedis is a chronic infection. Fungi grow and multiply in the stratum corneum. Long-term medication is required to completely eliminate it. Therefore, after the symptoms of tinea pedis are relieved, you still need to continue taking the medication. The skin's metabolic cycle is about 28 days, so the medication must be taken for more than four weeks. It is best to conduct fungal examination and culture, and it is considered cured only if the results are negative for three consecutive weeks.
