Black Spot On Foot

Black spots on the foot are plantar warts, named after the part of the body they show up on — the bottom of the foot. Plantar warts are singular and small, but they can grow in clusters called mosaic warts. One distinguishing feature is the small black spot that appears on the wart, referred to as seeds.

What is a black spot on the foot?

Plantar warts develop on the ball or the heel of the foot. At the center of the wart are black spots, these capillaries supply the blood. Both the wart and the black spots may be unsightly, creating discomfort, but they are not harmful. Individuals experience minor irritation or pain, depending on where the wart is on the foot.

These black spots are non-cancerous growths in the top layer of the skin. Although they are not dangerous to our health, they are contagious. They can be spread with skin-to-skin or surface contact. Children playing at the playground may come in contact with each other or touch a contaminated surface.

• Consider limiting where and when you walk barefoot.

The risks are rare for a healthy person, but they exist. Risks increase for individuals with weakened immune systems. If you have a history of plantar warts, your risks of recurring incidents are higher.

What causes a black spot on the foot?

The cause is a strain of the human papillomavirus (HPV), entering the body through small cuts or lesions on the bottom of the foot. This strain is not the same virus associated with genital warts. This virus speeds up the growth of skin cells, developing a hard skin cover. Sometimes plantar warts are confused with a callus until the black spot on the foot appears.

The pressure from standing or walking can cause warts to grow inward. Our immune system is prepared to fight these growths, so if the pain is bearable, they will disappear. The HPV virus can lay dormant for years and something will trigger it — causing a recurrence. Even after the condition is treated, the virus may stay in your body and erupt again with no warning.

If the pain persists, or redness and swelling develop, you need to see the doctor. It’s not a good idea to self-treat the condition. You could prompt more serious problems if an infection exists. Foot conditions can be related to heredity or a sign of another more threatening health condition.

Symptoms of black spots on the foot

Depending on the severity of the growth, you may notice a change in your normal stance while standing or walking. If you ignore the condition, it could cause muscle or joint issues. In some cases, the symptoms go undetected.

  • Black spot on the foot
  • Pain or tenderness when walking or standing
  • Thickened skin, like a callus

If the wart has spread to other areas — contact the doctor. The doctor needs to see the area to decide how much of wart has grown below the skin’s surface. Once the examination is completed, the doctor will determine the best form of treatment.

It’s rare, but there are times when the wart is misdiagnosis – never self-diagnosis health events. Make an appointment to see the doctor if any of these conditions exist.

  • You want the wart removed
  • The wart is growing larger
  • Treatment didn't remove the wart
  • Warts reappear shortly after treatment
