Creating Waves of Awareness
Corns arise not only from tight boots and shoes, but also from a certain disposition with some persons, which may be lessened by Antimonium crudum, Phosphorus, Rhus, Bryonia, Lycopodium, Phosphoric acid, and Sulphur, according to temperament, constitution and other circumstances. Relief may be obtained by bathing the feet in warm water and paring the corns closely, and applying Arnica plaster. If the corns pain much when the weather changes, take Rhus, sometimes Bryonia or Calcarea.

A corn (or clavus, plural clavi) is a specially shaped callus of dead skin that usually occurs on thin or glabrous (hairless and smooth) skin surfaces, especially on the dorsal surface of toes or fingers. They can sometimes occur on the thicker palmar or plantar skin surfaces. Corns form when the pressure point against the skin traces an elliptical or semi-elliptical path during the rubbing motion, the center of which is at the point of pressure, gradually widening. If there is constant stimulation of the tissue producing the corns, even after the corn is surgically removed, the skin may continue to grow as a corn. ~ Wikipedia
