So this bump on your foot isn’t going away. It hurts when you press on it and when you are working out in the gym. Is is a callus? Is it a wart? What is it doc?

Plantar warts are growths that often appear on the weight-bearing surfaces of your feet. This pressure also causes plantar warts to grow inward underneath a hard, thick layer of skin called a callus. So that wart is bump is probably BOTH a wart AND a callus. Plantar warts are caused by HPV. The virus enters your body through tiny cuts on the bottom of your feet.  Children often get warts because they haven’t built up an immunity to them.

Plantar wart signs and symptoms include:

  • A small, rough, or bumpy lesion on the bottom of your foot
  • Callus over a well-defined "spot" on the skin, where a wart has grown inward
  • Black pinpoints. These are actually small blood vessels
  • A bump that interrupts the normal lines in the skin of your foot
  • Pain or tenderness when walking or standing

See your doctor for the bump on your foot if:

  • The lesion is bleeding, painful or changes in appearance or color
  • Your pain stops you from doing what you want to do
  • You have diabetes or poor sensation in your feet
  • You also have a weakened immune system because of immune-suppressing drugs, HIV/AIDS or other immune system disorders

Transmission of the virus

Each person's immune system responds uniquely to HPV. Not everyone who comes in contact with it will develop warts. People in the same family react to the virus differently.

Risk factors

Anyone can develop plantar warts, but this type of wart is more likely to affect:

  • Children and teenagers
  • People with weakened immune systems
  • People who have had plantar warts before
  • People who walk barefoot where exposure to a wart-causing virus is common, such as locker rooms
