Calluses may be mistaken for corns. Unlike corns, calluses have no nucleus pressing on the nerve. Pain from calluses tends to be a wider spread burning sensation rather than the intense pain of a corn.
Calluses are larger than corns with a creamy yellow colour. They appear round or oval and have visible, ridged skin lines on the surface.
As with other foot ailments, ill fitting shoes, incorrect walking action and bone deformities (e.g. Bunions) can create calluses. If a callus becomes painful, professional advice must be sought from a podiatrist.
