It is common for an unremoved splinter in the hand to eventually turn into a corn. This occurs because if the splinter is not removed, it causes the body's tissues to reject the foreign object. This rejection leads to the formation of local tissue scars around the splinter, which can subsequently develop into a lump that resembles a corn. As long as the splinter remains in the body, the lump and scar will not disappear. Therefore, surgical intervention is necessary to excise the scar tissue formed under the corn to ultimately heal this condition.

Can corns be treated with corn plaster?

Corns themselves are caused by viral infections, and medically they are referred to as corns. Thus, they can be improved through medication. Corns also represent a type of local skin proliferation, so if you want to completely remove them, specific treatment is necessary to make improvements. Medications can achieve certain therapeutic effects, but it is relatively easy for them to recur after treatment. Therefore, in daily life, it is important to specifically enhance immunity, then avoid repeated outbreaks and local pressure to prevent recurrence. In everyday life, you can also go to a hospital or a specialized foot care center for specific local treatment. Complete cure is necessary to avoid repeated issues as much as possible. Additionally, once immunity is improved, the chances of recurrence will decrease.

What is the difference between a viral wart and a corn?

Viral warts and corns, though similar in appearance, have significant differences. In terms of cause, viral warts are caused by an infection of the human papillomavirus and are contagious. Corns, on the other hand, are not contagious and are caused by long-term pressure, friction, or tight shoes. In terms of treatment, corns can often be cured through laser treatment or medication. Viral warts need to be treated with antiviral medications, along with physical treatment methods such as cryotherapy with liquid nitrogen. (Please use medication under the guidance of a doctor)

Why do corns form on the feet?

Corns on the feet are caused by long-term compression or friction, leading to excessive proliferation of the stratum corneum and thickening of the stratum corneum. Corns commonly occur in adults, particularly in women, and are frequently found on pressure-bearing areas such as the feet, soles, the inner edges of the big toe, the outer sides of the little toes, as well as the heels and tips of the toes which are areas of friction and pressure. The skin lesions are clearly defined, either light yellow or deep yellow in color, shaped like a cone with a smooth and slightly raised surface. Because they compress the peripheral nerves in the dermis, walking or when pressure is applied, the pain is quite noticeable.

Why do corns keep increasing in number as they grow?

Corns growing in number and size is usually linked to wearing tight shoes and compression. They are also related to localized friction and irritation. Another possibility to consider when corns multiply is an infection caused by human papillomavirus resulting in plantar warts, which are similar in appearance to corns. Plantar warts are somewhat contagious and can also arise when the immune system is weakened. If your corns are increasing in number, it is important to promptly visit a dermatologist at a reputable hospital. Once a clear diagnosis is made, appropriate treatment options may include carbon dioxide laser therapy or cryotherapy using liquid nitrogen. If you are experiencing frequent corns, it is essential to wear loose-fitting shoes with soft soles, minimize walking, and avoid sitting for long periods.

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.
