Plantar warts are common warts that occur on the bottom of the foot. Plantar warts are superfluous growths that occur on the bottom of the foot. They are caused by HPV-1.3.4 virus infection and can be transmitted by self-inoculation through small breaks in the skin, thereby increasing their number. Plantar warts are easily transmitted by self-inoculation because of the daily stress on the sole of the foot and the friction of the shoes. The plantar warts can occur anywhere on the bottom of the foot, and the number is variable and the size of the damage varies. The combination of anti-proliferation and anti-viral drugs, combined with a high-pressure jet injector, is injected into the wart within minutes, and the wart will fall off on its own after 2 to 3 weeks. After treatment, it does not affect the patient’s normal daily life. The efficacy of the treatment is further enhanced when combined with oral and external Chinese medicine. High pressure injection is a new and different method from traditional injection. Using a special high-pressure syringe imported from abroad, it does not have a needle but injects the medicine evenly into the patient by means of compressed air in a high-pressure jet. This simplifies the treatment operation, greatly improves the injection efficiency, and avoids the disadvantages of leaking the drug and uneven injection due to high pressure during injection. Each injection takes only 1 to 2 minutes, and the injected drug can be immediately visible in the wart. There is no pain for the patient, and the doctor’s operation is very effortless and quick. An important reason for the occurrence of corns is that the shoes do not fit or do not conform to the engineering principle of the foot, such as shoes too tight or heel too high, will squeeze a part of the foot, resulting in repeated pressure on this part; such as shoes are too loose, the foot will easily slide in the shoe friction, stimulating corneal growth to form a thick callus. Because the design of women’s shoes often seek novel styles, beautiful shapes, and ignore the principles of ergonomics, so the design of shoes with narrow faces, toe tips, and high heels, and these inappropriate shoes on the foot is easy to cause the toes to twist, turn out and improper extrusion of the sole and toes, therefore, the chances of corns occurring in women are much higher than in men. Since corns are mainly related to friction and extrusion between shoes and feet, the most effective prevention is to wear shoes that fit comfortably and do not have a sense of pressure, and the toes should have some room to move. At the same time, you should have two or three pairs of suitable shoes to wear in rotation, because the degree of pressure on the foot or parts of different shoes may be different, so as to avoid long-term pressure on the same part of the long corns. If conditions permit, you can also put some foam pads with holes in the corns or parts of the foot that are often under pressure to help reduce the pressure. For the corns that have grown, it is advisable to soften the affected area with hot water first, disinfection measures should be done, the surface keratin layer should be carefully peeled off with a small blade to reveal the corns, and the surrounding skin should be protected with adhesive tape, then under the guidance of a doctor, apply keratin-dissolving preparations, such as corns, levulinic acid ointment, vincristine ointment, urea ointment, etc., and repeat once every 2 to 3 days until the tip is exposed, then the doctor should use a sharp scalpel to Then the doctor will dig out the corns with a sharp scalpel. Do not dig with scissors to avoid skin infection or ulceration. Particular attention should be paid to patients with poor eyesight or those who already have peripheral blood circulation disorders, such as diabetes, coronary heart disease or varicose veins in the lower extremities.
