”A wart is a superfluous epidermis caused by HPV (human papilloma virus) infection of the skin or mucous membranes. These include common warts, plantar warts, flat warts and condyloma acuminata. The most important thing that you can do is to get a good idea of what you are looking for. It is commonly found on the front of the toes and soles of the feet. Due to the pressure on the nerve endings at the tip, it is painful and affects walking. The “foot pad” or “callus”, also known as callus, is a flat hypertrophic plaque of skin on the hands and feet caused by long-term skin compression and friction, waxy yellow, hard and slightly transparent, with unclear boundaries, thick in the center and thin at the edges. Prevalent in the palmoplantar, often symmetrical occurrence. Mostly no conscious symptoms. It is important to reduce friction and compression of the foot, wear suitable soft-soled shoes or use soft insoles. The surface of the plantar warts is thickened, and when the keratin layer is removed with a knife, the soft core of the keratin is visible and there are many small black dots on the surface. The corns are inverted conical keratinous hyperplasia, pain is obvious when walking; while the foot pad is flat flaky keratinous thickening, the range is wider, generally not painful. The actual fact is that the footpad is a protective response and does not require treatment. The actual fact is that you can get a lot more than just a few of the most popular and popular items. The actual fact is that you can use 5-fluorouracil ointment, 10% formalin, 20% glacial acetic acid or concentrated carbolic acid to apply topically to the lesions twice a day. You can also choose 40% iodine (herpes net), dimethylsulfoxide solution and 20% to 40% iodine cream topical application plus sealing package. Or herbal infusion can also be cleared. For patients with small numbers, physical therapy such as microwave, freezing and laser is the main treatment. Pay attention to avoid pressure and friction to prevent secondary septic infection. The treatment of corns can be topical corns cream: first soak the affected area with hot water, peel off the superficial keratinous hyperplasia part, and as far as possible, carefully peel off the central corns plugs, and apply the corns cream to this core part. Change the medication once a week. Before changing, peel off the white part of the dip until the damage is removed. The affected area can also be frozen with liquid nitrogen, and the cotton swab method and spray method can be used. Fire needling and black plucking sticks can also be used. For protection, appropriate footwear and shoes with sponge or cotton padding should be worn to reduce friction and pressure.
