Plantar corns are usually caused by local squeezing or friction, and patients have obvious squeezing pain, which can be very painful when walking on a daily basis. There are more ways to treat corns on the soles of the feet, depending on the specific situation, medication or surgery: 1. Medication: When the corns are painful and large, and the patient is unable to handle them by himself, it is recommended to go to the hospital and treat them with medication under the guidance of a professional doctor. Usually, an erosive agent such as cornsite cream is used to loosen and melt the cornsite and clean it. At the same time, it is necessary to use iodophor to sterilize and anti-inflammatory to the wounded area to avoid infection. 2. Surgical treatment: In the case of fruitless medication, it is recommended that patients go to the hospital and have a surgical plan formulated by a professional doctor. Surgery mainly includes carbon dioxide laser, liquid nitrogen freezing treatment and anesthesia excavation, along with topical application of vitamin A acid cream. After the liquid nitrogen cryotherapy, some patients may have blisters and blood blisters, and if they are large, they can be sterilized and the herpes fluid extracted. Patients need to pay attention to choosing suitable and comfortable shoes, keeping the feet clean and dry, as well as abstaining from spicy and stimulating foods to aid recovery after treatment. After the treatment is healed, soft and thick-soled shoes should also be worn to reduce the possibility of recurrence of corns.
