Complications
By Mayo Clinic staffPlantar warts can be persistent. They can shed the virus into the skin of your foot before they're treated, prompting new warts to grow as fast as the old ones disappear. The best defense is to treat new warts as quickly as possible so that they have little time to spread.
If untreated, warts can enlarge and spread, developing into clusters of warts called mosaic warts. They may also become extremely painful. If you have lots of plantar warts, the pain may make it difficult for you to walk or run.
