Methods of removing corns on feet include medication, physical therapy and surgery. 1. Medication: Use corns cream or 50% salicylic acid to treat the local area. Before changing the medication, you should soak your feet in hot water to soften the area and scrape off the softened keratin, but protect the surrounding skin. 2. Physical therapy: mainly includes liquid nitrogen cryotherapy and laser therapy, through non-surgical modification of the corns skin area, eliminating the thickened keratin, which is conducive to recovery. 3. Surgery: If the above treatments are ineffective or the symptoms are more serious, surgical excision should be considered to remove the corns completely. In the process of treatment, it is necessary to follow the doctor’s instructions, safe and reasonable use of medication, and to do a good job of daily care, wear appropriate shoes to avoid long-term friction and pressure on the soles of the feet, to prevent repeated attacks of corns.
