Corns

Corns are usually caused by shoes that don't fit properly. Shoes that are too tight, or pinch, put pressure on the bony areas of the foot and also interfere with the circulation of blood ultimately leading to corns.
Easy Home Remedies 
The sap from a marigold stem, milky juice from green figs or papaya juice are all good remedies. Apply to the affected area frequently. 
A slice of lemon can be placed on the corn and bandaged in place overnight.
