Description

Corns are calluses that form on the toes because the bones push up against the shoe and put pressure on the skin. The surface layer of the skin thickens and builds up, irritating the tissues underneath. Hard corns are usually located on the top of the toe or on the side of the small toe. Soft corns resemble open sores and develop between the toes as they rub against each other.

Causes

• Improper fitting shoes. This is the number one reason for callus formation. Shoes that are too tight squeeze the foot increasing pressure. Shoes that are too loose may allow the foot to slide and rub creating friction.
• Toe deformities including hammer toes and claw toes increase the risk of corn and callus development
• High heeled shoes – increase the pressure on the forefoot
• Rubbing against a seam or stitch in your shoe.

Treatment

Most patients get great relief from conservative treatment of corns/callus

• Corn pads (donut shaped foam pads) over the corn with help relieve pressure.
• Orthotics to offload the corn if located on the bottom (plantar) aspect of the foot
• Proper fitting shoes
• Soaking your feet regularly and using a pumice stone or callus file to soften and reduce the size of the corn and calluses.
• Your doctor may trim the corn by shaving the dead layers or skin off with a scalpel or performing a larger excision if needed.
  • This type of procedure should be done by professional, particularly if you have poor circulation, are diabetic, poor eyesight, or a lack of feeling in your feet.
• Antibiotics may be needed if there is an underlying infection from an open callus
