The painful lesion you may have at the bottom of your foot is known as a wart but the scientific term is a verruca vulgaris. They are usually caused caused by a viral infection of the skin. This occurs as a result of direct contact with the virus. Contact usually happens in dirty areas such as locker rooms. If your feet are typically sweaty, you can be predisposed to getting a wart.
Warts can be extremely painful, but they’re often times confused for a callus. The main difference between the two is that warts are painful when pinched and with direct pressure whereas calluses only hurt with direct pressure. Warts also tend to cluster in a mosaic pattern and small pinpoint redness can be seen.
Treatment of your wart can be done in the office. Usually, over-the-counter medications have a difficult time penetrating the thick skin on the bottom of the foot, so they do not work well in this area. Your podiatrist’s treatment usually consists of burning the wart with topical acids, freezing with liquid nitrogen, laser surgery or surgical removal. All methods have the possibility of the wart coming back. Surgical excision of the wart has the highest success rate with a relatively low rate of recurrence. There is some mild discomfort with this procedure and it takes several treatments over weeks for the area to completely heal depending on the severity. You activity is usually not affected by the treatment.
