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.

Can corn plaster be used on warts?

Warts, commonly referred to as corns, are caused by viral infections. This condition is somewhat related to the individual’s immune system, so physical therapy can help improve the situation. Corn plasters can be effective for treating warts, but it is essential to avoid overusing them to prevent local damage and other issues. Additionally, there are other treatment options for warts, such as laser surgery, which can effectively address the problem. Surgical removal with a scalpel or podiatry knife can also completely eradicate the wart. Adapting the treatment method based on specific changes can lead to quicker recovery; however, it is crucial to prevent any infections associated with warts.

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.

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.

What should I do if a splinter in my hand that wasn't removed has grown into a corn?

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.

Do corns that don't hurt need to be treated?

Corns are mostly caused by the entry of foreign objects into the skin locally, followed by hyperplasia formed through repeated friction, generally appearing as wedge-shaped on the surface of the skin. If corns are not treated, they might gradually grow larger or increase in size, causing pain during long-term walking. Even if there is no pain temporarily, treatment is still necessary. It is advised to go to the dermatology department of a regular hospital for surgical removal or use liquid nitrogen freezing. This condition can be prevented from recurring by paying attention to one’s walking posture, shoe-wearing habits, and avoiding stepping on dirty things. Regular exercise to strengthen immunity and avoiding walking barefoot are also beneficial.
