Patient's question:
NoDoctor's answer:
A corn is a repeated mechanical trauma to the foot that can cause hyperkeratosis, leading to localized thickening of the skin and causing pain and discomfort in the foot, affecting walking. Therefore, active treatment is required. Generally, corn ointment is applied externally. After use, if the skin's keratin layer thickens, it should be trimmed, and then the corn ointment should be continued to be applied. It usually takes three consecutive uses to heal.
