Corns are not easy to be cured and are prone to recurrence. The cause of the disease can be removed through daily care and active treatment, so that the patient can return to normal. When the skin of the foot is rubbed and squeezed for a long time, such as wearing inappropriate shoes for a long time, standing or walking for a long time, it is easy to lead to the occurrence of corns. It is more difficult to cure corns. The first step in treating corns is to remove the causative factors and avoid triggering factors, and then remove corns through daily care and medication, physical and surgical treatments, as well as minimize recurrence. Daily care includes avoiding prolonged walking, wearing loose and soft shoes, and soaking feet in hot water. Medications for corns include corns cream, salicylic acid ointment, and urea ointment, all of which should be used as prescribed. Laser treatment, cryotherapy, and surgery are also available to remove corns.
