Black Spots On Bottom Of Feet

Black Spots On Bottom Of Feet

Few things cause black spots on the bottom of the feet. It is not dangerous or life-threatening most of the time but one must visit a doctor if black spots are visible on the bottom of feet.

Black Spots On Bottom Of Feet

1. Calluses

Calluses are a build-up of hard skin, generally beneath weight-bearing bony surfaces. Calluses generally occur on the surface under the foot. Some degree of callus formation on the sole is normal.

What causes calluses?

Calluses are caused by an uneven distribution of weight, generally on the bottom of the forefoot or heel. Calluses can also be caused by improperly fitting shoes or skin abnormalities.

How can calluses be prevented?

Wear properly fitting, supportive shoes with shock-absorbing soles; avoid leather-soled shoes.
Use cushioned pads and insoles.
Limit periods of barefoot walking.

How can calluses be treated?

If you have a callus, do not try to cut it or remove it with a sharp object. Instead, soak your feet first in lukewarm, soapy water, and then use a pumice stone to gently remove the build-up of tissue. Use cushioned pads and insoles. Medications may also be prescribed to soften calluses.

When other treatments have not been successful, surgery may be recommended. Corrective surgery involves removing internal pressure by removing a piece of the bone or changing the position of the bone so calluses do not form.

2. Plantar warts

Plantar warts look like calluses on the ball of the foot or heel. They may appear to have small pinholes or tiny black spots in the center. They are usually painful and may develop as a single wart or in clusters.

What causes plantar warts?

Plantar warts are caused by a viral skin infection that occurs on the outer layer of skin on the soles of the feet.

How can plantar warts be prevented?

Because it is unknown how the wart virus is transmitted, it is best to avoid direct contact with warts from another person or from one part of your body to another.
Limit periods of barefoot walking.

How can plantar warts be treated?

Do not use over-the-counter medications to dissolve the wart. If you are not sure if you have a plantar wart or a callus, let your doctor decide.

Plantar warts are difficult to treat with a 100 percent cure rate, since warts generally have an average lifespan of about 18 months, depending on the infecting virus. There is no vaccine to prevent plantar warts.

In a doctor’s office, topical medications and pads are often used to soften the thickened skin and relieve some discomfort. Freezing the plantar wart with liquid nitrogen is another form of treatment. Surgery may also be considered when other treatment methods are not successful.

These are both major causes of black spots on the bottom of feet.
