While they can appear anywhere on the foot, corns are most common on toes. Corns can also appear as secondary problems from other foot issues, such as bunions.
Corns are unsightly, painful & professional treatment is the only remedy.
Corns -otherwise known as clavus- are distinctively shaped sections of callus. Circular in appearance with a centre that resembles a barley seed, it can become intolerable to walk in severe cases.
As with callus, repeated friction and pressure are the causes for corns. They mostly appear on the toe joint, but can develop on the soles as well.
While not particularly serious on the surface, diabetics and those with heart issues face complications with foot ailments & should never attempt to treat corns themselves.
