Corns are primarily caused by the prolonged and repeated irritation from foreign objects entering the skin, and they are also somewhat related to one’s walking habits or footwear. Once formed, they can be painful, and in severe cases, may lead to pus-filled infections. Typically, corns can be effectively treated with common corn plasters.

If the treatment with corn plasters proves ineffective, one can seek cryotherapy with liquid nitrogen at a dermatology department in a standard hospital. In more severe cases, surgical removal may be necessary. Generally, corns can be completely cured using these methods. It is advisable to wear loose-fitting shoes regularly, avoid tight shoes that compress the feet, and not walk barefoot to prevent foreign objects from re-entering the skin and causing a recurrence of the condition.

The difference between plantar warts and corns

Toe warts and corns are both skin diseases that occur on the feet, but they are entirely different diseases, and many people easily confuse toe warts with corns. First, the causes of toe warts and corns are different. The occurrence of corns is greatly related to compression and friction, while toe warts are mainly caused by viral infections due to reasons such as low immunity. Secondly, their contagiousness is different; corns are not contagious, while toe warts are highly contagious.

Is a corn the same as a callus?

Skin tags are not the same as corns; they are two completely different conditions. Skin tags generally refer to abnormally proliferating tissue at the nail area, and also commonly refer to warts. Corns usually result from localized abnormal friction, causing proliferative growth of the soft tissue, typically located on the sole of the foot. Skin tags and common warts can also occur on the bottom of the feet, but skin tags usually appear as proliferative, tumor-like protrusions on the surface of the skin, whereas corns generally do not protrude above the surface of the skin.

What medicine to buy for a corn?

Corns are a type of skin disease formed due to long-term friction and compression. The cause of corns is often related to standing for long periods or wearing ill-fitting or tight shoes. For treating corns, it is advised to primarily use topical medications, which can be directly applied or used as a corn plaster. Besides topical creams, some physical treatments such as carbon dioxide laser, cryotherapy, and X-ray irradiation can also be used.

Corns are treated in which department?

Corn is a relatively common condition. If you suffer from corns, it is recommended to consult dermatology or surgery for treatment. Corns are mainly caused by prolonged standing, or by wearing shoes that do not fit properly or are too tight. They usually appear individually. It is advised to seek treatment promptly at the dermatology or surgery department of a hospital. The primary treatment involves topical medications, but methods like laser or cryotherapy can also be employed.

Are corns and calluses the same thing?

Corns and calluses are generally different diseases. Generally speaking, corns are caused by long-term local compression and friction. In this case, it will lead to thickening changes in the stratum corneum, so it is relatively easy for this problem to occur on the soles of the feet. Warts, on the other hand, are a type of common wart caused by viral infection. This means that infections are more likely to occur when the body's immunity is low. Of course, this is also directly related to local discomfort or compression problems. However, there is an essential difference between the two diseases. Nevertheless, the general direction or principle of treatment for both diseases is similar, mainly involving local excision methods. Additionally, appropriate use of antivirals, or treatments such as laser therapy or cryotherapy, can also achieve the purpose of treatment and improvement.
