Thanks for writing in, Corns are generally due to abnormal pressures or prolonged pressure at particular site. They could be due to change in footwears, prolonged standing, wet feet etc. Most of them disappear gradually. Try changing footwears. Keep your feet dry. Avoid prolonged standing. If the corn is too painful and not responding to corn caps, then best is to consult orthopaedician or general surgeon who can remove it by a minor surgery. Hope this helps you. Get well soon.
