Verruca (Plantar Warts)

Plantar Warts (Verruca) a found most commonly on the bottom or ‘plantar’ area of the feet. Warts are caused by a virus that is common and grows in warm moist environments such as change rooms and pool areas. There are several different types of warts that affect the feet and they all present in a variety of ways. They could appear alone, in several areas of the foot, or grouped in clusters. They could also form a solid mass that becomes very thickened and will take up a large area of the foot.

Most of the time, what you see on the surface of the skin is only a small fraction of the actual size of the wart. Much like an iceberg, the largest part is found below the surface. Warts can be very painful or you may never even know you have one. We worry more when people are not aware they have warts and could be spreading the virus without even knowing it. It is important to inspect your feet on a regular basis for any lesion that looks suspicious, and attend the foot clinic to see what the best course of action is for you.

We recommend covering any warts, even those undergoing treatment, with a water-proof bandage during barefoot activities in order to prevent spreading the virus. Check other family members to make sure that they have not picked up some warts from sharing a shower at home. All infected individuals in the home should be treated at the same time.

There are some drugstore remedies available that seem to have limited effectiveness on plantar warts. If the wart is new and very small, you may want to try an over-the-counter remedy to see if that eliminate the wart. If it continues after several weeks, or if you see more, or if other members of your family get them, then it is time to come to the foot clinic. Here at the Kingston Foot and Ankle Clinic we have several types of topical treatment specific to your type of plantar wart. Often as little as 2 or 3 treatments are needed, depending on how long it has been there.

If you have been treated at the clinic, you will experience a blister formation under the skin, under the wart, that attacks the part that is hard to see. These can be quite painful for a few days and it is best to try and avoid being on your feet for long periods. Wear comfortable footwear and you can tape or add felt pads for cushioning during this period.

You will be advised that there is no risk of infection at that point, although sometimes it looks purple or yellow around the warts and can appear red with inflammation. It will also be advised to avoid puncturing the blister as this can let bacteria into the site. After a few days, the blister will subside and be more comfortable. If in doubt, please feel free to call the clinic.
