Calluses are our body’s reaction to pressure
Calluses are common on the bottom of the feet. Calluses are our body’s reaction to pressure by building up the skin over the parts of the foot that bear more weight or rub in our shoes. These calluses can buildup to the point of becoming painful and require treatment. Sometimes you can develop a certain kind of callus called a porokeratosis.
A porokeratosis, also known as a seed corn, are calluses with a central hard core the size of a small seed. These lesions are small but painful and can feel like you are walking on a small pebble. These types of calluses can occur in areas of pressure, where your foot bears weight, but they can occur anywhere on the bottom of your foot. This condition often resembles a plantar wart, so it is important to see a podiatrist for proper diagnosis.
Treatment of these lesions involves debridement of the lesion by a skilled podiatrist as well as offloading areas of pressure that may be contributing to the formation of callus. Topical chemical treatments such as used for warts may also be considered as well as a urea cram, a strong cream that will soften the callus tissue. These lesions, like other calluses, are more than likely to come back but can be managed by your podiatrist to keep you out of pain.
