Signs and symptoms of plantar warts include:

  • Small, fleshy, grainy lesions, or growths, on the soles of your feet
  • Hard, thickened skin (callus) over a well-defined "spot" on the skin, where a wart has grown inwards
  • Black pinpoints, which are commonly called "wart seeds" but are actually small, clotted blood vessels
  • Lesions that interrupt the normal lines and ridges in the skin of your feet
  • Pain or tenderness when walking or standing

When to see a doctor

See your doctor if:

  • The lesions are painful or change in appearance or color
  • The warts persist, multiply or recur, despite home treatment
  • The warts interfere with your activities
  • You have diabetes or nerve damage (neuropathy) in your feet — in which case, you should not use at-home treatments
  • You have a weakened immune system because of HIV/AIDS, immune-suppressing drugs or other immune system disorders
  • You have any doubt that the lesion is a wart

In these cases, your doctor may prescribe a closely monitored treatment plan or consider a different diagnosis.
