Corns are circumscribed, horny, conical thickenings with the base on the surface and the apex pointing inward and pressing on subjacent structures.
Hard corns, which occur on the dorsa of the toes or on the soles
Soft corns, which occur between the toes and are softened by the macerating action of sweat
Corns arise at sites of friction or pressure, and when these causative factors are removed, they spontaneously disappear.
Bony spur or exostosis is present beneath both hard and soft corns of long duration, and unless this exostosis is removed, cure is unlikely
Wearing ill-fitting shoes. Tight shoes and high heels can compress areas of your feet. When footwear is too loose, your foot may repeatedly slide and rub against the shoe. Your foot may also rub against a seam or stitch inside the shoe.
Skipping socks. Wearing shoes and sandals without socks can cause friction on your feet. Socks that don’t fit properly also can be a problem.
Playing instruments or using hand tools. Calluses on your hands may result from the repeated pressure of playing instruments, using hand tools or even writing
- A bunion is an abnormal, bony bump that forms on the joint at the base of your big toe.
- A hammertoe is a deformity in which your toe curls like a claw.
- Other foot deformities.Certain conditions, such as a bone spur, can cause constant rubbing inside your shoe.
- Not protecting your hands.Using hand tools without wearing gloves exposes your skin to excessive friction.
The relief of pressure or friction by corrective footwear or the application of a ring of soft felt wadding around the region of the corn will often bring a good result.
Soaking the feet in hot water and paring the surface by means of a scalpel blade or pumice stone leads to symptomatic improvement
