Calluses are areas of hyperkeratosis, or overgrowth of skin tissue. The skin thickness and hardens. Calluses most commonly form on the feet and sometimes on the hands.

Corns are small cone-shaped areas of skin overgrowth that most often form on or between the toes. They can be either soft or hard. If they form between the toes, the moisture of the area keeps them soft; corns that form on top of the toes are typically hard.

• These growths can cause inflammation and pain.
• Corns especially may ache and be tender to the touch.
• Both corns and calluses usually form in response to repeated friction or pressure, such as from wearing ill-fitting shoes or performing certain tasks repeatedly.
• Other factors that may be involved include staphylococcus-or streptococcus-type in-faction, misalignment of the foot, and an acid/alkaline imbalance in the body.
• The heavy consumption of fats, sugars, and highly processed foods is the most common cause of imbalance in the acidity and alkalinity of the body.
