FHN - Calluses Calluses formation is an accumulation of dead skin cells that harden and thicken over an area of the foot. This callus formation is our bodies defense mechanism to protect the foot against excessive pressure and friction.
Some calluses have a deep seated core known as a nucleation.
This particular type of callus can be especially painful to pressure. This condition is often referred to as Intractable Plantar Keratosis. Calluses develop due to excessive pressure at a specific area of the foot. Many people try to alleviate the pain caused by calluses by cutting or trimming them with a razor blade or knife. This is not the way to properly treat calluses.
