Corns are a common skin disease, closely related to prolonged standing or constant friction and compression under the feet. Corns consist of a hyperkeratosis forming a circular or oval, yellowish appearance. They generally cause severe pain once they develop, and prompt treatment is necessary. This can include the use of topical medications or physical therapy methods, such as laser treatment.

How can corns be treated to be eradicated completely?

Corns are growths formed by the entry of foreign bodies into the skin, which become exacerbated by repeated friction and compression. There are many treatments for corns, and the most conventional one involves the application of corn plasters, which can completely cure the condition. Corn plasters are a type of corrosive medication. After local application, they completely erode the corn. However, in some patients where the corn is particularly deep or large, corn plasters may not be able to cure it completely. In such cases, it is advisable to visit a dermatologist at a reputable hospital and opt for liquid nitrogen freezing treatment. Following liquid nitrogen treatment, blisters form locally, and as these blisters peel off and necrotize, the corn also falls off and dies. If these treatments are not effective, one can consult a surgical department for a surgical procedure to completely excise the corn.

The difference between corns and calluses.

Firstly, a corn is a type of common wart, and it actually has clear differences from a callus. Common warts generally occur on the soles of the feet, or on the proliferative protruding surface, typically characterized by specific manifestations. In such cases, there usually are also prominent manifestations, and these conditions can also cause some minor pain. On the other hand, calluses are completely the opposite of corns. The surface of a callus is generally not protruding, meaning the skin is flat and usually quite smooth. In this respect, there is a fundamental difference on the surface. Moreover, calluses can potentially be caused by local compression factors. As for corns, they are usually caused by lowered immunity. That is, viral infections are what lead to the problem of corns.

What causes corns on the soles of the feet?

Corns are mostly caused by the prolonged and repeated friction and compression of a foreign object that has entered the skin, resulting in a hyperproliferative lesion. They are generally small and can be completely treated with common corn ointments. However, if a corn has been present for a long time and has grown larger, it is recommended to seek treatment at a formal hospital's dermatology department using the method of liquid nitrogen freezing, which usually resolves the issue in one or two sessions. Some corns can become larger and may be painful or show signs of inflammation and infection. In such cases, it is advisable to visit a surgical or dermatology department for a minor minimally invasive surgery to completely remove it. When wearing shoes, it is essential to choose loose and soft-soled footwear, and avoid walking barefoot on surfaces to prevent foreign objects from entering and causing the recurrence of corns.

There are many small flesh spikes in the corn.

Corns often contain many small flesh spikes, and this condition might be due to plantar warts, caused by factors such as local compression and friction. This disease is actually a type of common wart, usually resulting from abnormal local skin proliferation, leading to keratinization. Physical therapy or surgical methods are generally used to improve this condition. Physical therapy mainly involves excision and separation, and it is essential to use some softening solutions to prevent extensive bleeding. Surgical options mainly include laser and cryotherapy, which can effectively treat and improve the condition, and further analysis and determination can be done based on the specific situation.

Differentiation between Corns and Plantar Warts

Corns and plantar warts are two different skin conditions, although both often occur on the feet, they have significant differences. First, corns and plantar warts differ in contagion and quantity. Generally, corns appear singly and are not contagious; while plantar warts often appear in larger numbers and are highly contagious. Moreover, corns are usually caused by pressure or friction on the feet, whereas plantar warts are caused by a viral infection of the skin on the soles of the feet.
