Picture of corns on toes
Corns and calluses are areas of skin that have thickened due to pressure. Calluses are actually a normal way for the human body to protect itself. For example, the pads of the hands will develop calluses when working out with weights if they are not protected. If these calluses are not created the skin could tear or be vulnerable to the constant pressure on the region – it is a normal and natural way for the skin to protect itself. In the foot, in particular the toes, in areas of high pressure the skin will thicken up to protect itself. This becomes problematic as the pressure continues. The skin thickens further eventually becoming painful and then gets treated as something foreign to the body.
This person most likely has experience pressure from footwear that has created the corns in these specific areas on the foot. This individual also has signs of athletes foot, a foot fungal that is common in sports athletes (as seen between the 3rd and 4th toe). This could indicate unhygienic feet which could be contributing to a number of foot problems for this person.
Picture of corns on foot
This picture shows a foot that has both a bunion and a corn on it. This type of occurance in not uncommon. It is true that anomalies like bunions and hammertoes in feet can encourage feet to develop corns and calluses. This is due to additional pressure being created between toes, within shoes, or even against the ground. Corns and calluses created because of foot abnormalities can be treated and removed, although the corns will likely return until the source of the problem has been addressed. Surgical solutions are available for most foot disfigurements. See your doctor for medical advice.
Picture of a corn on the sole of a foot
This image shows a plantar corn on the sole of a foot. Again, similar to the other pictures of corns, corns are created from pressure, and in the case of this individual, it is likely no different. It is however possible that a plantar wart developed under the sole of the foot, and after time the friction and irritation over the wart created a callus over top of the wart. Warts are best treated by freezing with liquid nitrogen, although a callus over top will protect the wart from the freezing, and similar methods for removing corns can be used to remove calluses over warts before the wart can be frozen.
