Diagnosis
Your podiatrist will diagnosis a plantar wart based on physical exam and description of symptoms.
Treatment
If your doctor determines that your wart needs to be treated, the usual choice of therapy is salicylic acid, which when applied daily eventually softens the skin layers of the wart so that it can be peeled off. This process may take several weeks or months. Other treatment options for plantar warts include injection with medication, freezing with liquid nitrogen, and surgical removal. In children, a removal method using duct tape may be effective and relatively painless.
Without Treatment
Sometimes plantar warts go away on their own if left untreated. However, many warts can become larger, more painful, and can even begin to multiply into clusters of warts called mosaic warts. Walking and running will become difficult in these situations. Over time, some plantar warts can lead to a type of skin cancer.
