- Repeated HPV exposure. For example, walking barefoot in public locker rooms and common public areas.
- In some cases, the virus can be transmitted to the feet from other areas of the body. This is called remote location seeding.
When first diagnosed, individuals often feel a “lump” on the bottom of the foot when standing, similar to having a stone in the shoe. If left untreated, plantar warts can grow up to 1 inch in circumference and may spread into clusters (called mosaic warts). In severe cases, they cause a change in gait or posture that results in leg or back pain.
If you suffer from plantar warts, visit your podiatrist to find effective treatment options for you.
