Plantar Warts: Symptoms, Treatment, and Care - Dermatology

More Info

---

Plantar warts, also known as verrucae plantaris, are benign growths caused by the human papillomavirus (HPV) that typically appear on the soles of the feet. Understanding the symptoms, treatment options, and care for plantar warts is essential for effective management and relief.

1. Symptoms of Plantar Warts:
Plantar warts often present as small, rough, raised bumps on the soles of the feet. They may have a grainy appearance and can be surrounded by calloused skin. One of the hallmark symptoms is pain or tenderness when pressure is applied, especially when walking or standing. The presence of white spots or small dots within the wart can indicate the presence of tiny blood vessels, which may bleed when the wart is irritated.

Regarding your concern about the new white spots appearing near the existing wart, it is possible that these could also be plantar warts, especially if they are painful upon pressure. However, they could also be other skin conditions such as corns or calluses. A healthcare professional can provide a definitive diagnosis.

2. Treatment Options:
Common treatments for plantar warts include topical treatments, cryotherapy (freezing), laser therapy, and surgical removal. Over-the-counter treatments often contain salicylic acid, which helps to gradually peel away the wart.
As for using iodine (碘酒) and gentian violet (紫菌素), these are not standard treatments for plantar warts. While iodine has antiseptic properties, it does not have proven efficacy against HPV. Gentian violet is an antifungal and antibacterial agent but is not specifically indicated for warts. It is essential to consult with a healthcare provider before applying any topical treatments, as they can provide guidance on the most effective and safe options.

3. Continuous Application of Treatments:
If you choose to use topical treatments like salicylic acid, consistency is key. Regular application as directed can lead to gradual improvement and eventual resolution of the wart. However, if you are using iodine or gentian violet, it is crucial to monitor the area for any adverse reactions or lack of improvement. If the wart does not respond to treatment or if you experience increased pain, swelling, or other concerning symptoms, it is advisable to seek medical attention.

In summary, plantar warts can be painful and bothersome, but they are treatable. If you suspect that the new white spots are also warts, or if you have concerns about the effectiveness of your current treatment, it is best to consult a healthcare professional. They can provide a proper diagnosis and recommend an appropriate treatment plan tailored to your specific situation. Additionally, maintaining good foot hygiene and avoiding walking barefoot in communal areas can help prevent the spread of HPV and the development of new warts.
