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.

How does a corn form?

Corns are a common dermatological disease, mainly caused by friction and compression. They typically appear as small, round, hard lumps that are painful to press with the hand. They often occur on the soles of the feet or toes. Corns are usually caused by wearing shoes that are too tight or by standing for prolonged periods, which irritates the skin of the feet over time. Once corns develop, they must be treated promptly; otherwise, the pain may affect walking or make it impossible to walk.

What is a corn like?

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.

Can corn plasters be used for warts?

Warts are commonly caused by a viral infection and are a type of common wart. These warts can be removed or improved through physical treatments or medications, such as laser or cryotherapy. Using corn plasters can also be effective in these cases. Because the affected area is stimulated, there might be a noticeable change. If this change can be effectively managed, it can lead to successful treatment. Corn plasters can achieve this therapeutic effect. Although corn plasters are not highly specific, they do have some therapeutic effects. Furthermore, it is advisable to enhance the immune system. Specific antiviral treatments can be more effective and can be combined with other methods to judge and treat the condition. (Medication should be used under the guidance of a professional doctor.)

What will a worsening corn turn into?

Severe deterioration of corns usually affects walking. When corns appear, treatment options include using corn ointment, choosing carbon dioxide laser treatment, or cryotherapy with liquid nitrogen. Corns mainly result from prolonged compression and friction of the soft tissues of the sole, leading to this skin condition and causing localized pain. If corns develop, it is important to rest and avoid standing or walking for long periods. Also, avoid wearing shoes with very hard soles to prevent the recurrence of corns. When dealing with corns, soaking the feet in warm water to promote blood circulation and prevent the thickening of the skin can be beneficial. Diet-wise, it is advisable to choose low-fat foods.

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.
