Plantar warts are viral skin growths that develop on the bottom of the feet. Pressure from standing and walking may push them deeper into the skin, causing tenderness or the feeling that you are stepping on a small object.
At Preferred Footcare, our podiatrists provide professional plantar wart treatment in Stamford, Connecticut. We confirm whether the growth is a wart, evaluate its size and location, and recommend treatment based on your symptoms and medical history.
If a painful growth on your foot is spreading, keeps returning, or has not responded to home treatment, call (203) 975-9600 or request an appointment with Preferred Footcare.
Request an AppointmentWhat Is a Plantar Wart?
A plantar wart is a noncancerous skin growth caused by certain strains of human papillomavirus, commonly known as HPV. The virus enters through small cuts, cracks, or weakened areas of skin.
Unlike warts on other parts of the body, plantar warts are repeatedly exposed to pressure from standing and walking. This pressure may cause the growth to extend inward beneath a thick layer of skin.
A single plantar wart may develop, or several warts may grow together in a cluster. A group of closely connected plantar warts is known as a mosaic wart.
Plantar warts can affect anyone, but they are more common among children, teenagers, people who frequently walk barefoot in communal areas, and individuals with weakened immune systems.
What Causes Plantar Warts?
Plantar warts develop after the skin comes into contact with a strain of HPV that affects the feet. The virus may enter through a small cut, crack, scrape, or area of softened skin.
Possible sources of exposure include:
- Public swimming pools
- Communal showers
- Locker room floors
- Gym changing areas
- Shared exercise spaces
- Walking barefoot in damp areas
- Direct contact with a wart
- Sharing socks, shoes, or towels
- Using the same foot-care tools on affected and unaffected skin
Not everyone exposed to the virus develops a wart. The immune system responds differently from person to person, and a wart may not appear until weeks or months after exposure.
The virus can also spread from one area of the foot to another. Picking, scratching, shaving, or cutting a wart may contribute to this spread.
Plantar Wart Symptoms
A plantar wart may be confused with a corn or callus because each can create an area of thickened skin on the foot.
Possible signs of a plantar wart include:
- A rough or grainy growth on the sole
- A fleshy area covered by thickened skin
- Tiny dark dots within the growth
- Interrupted natural skin lines
- Pain when standing or walking
- Tenderness when the sides are squeezed
- A feeling that something is inside the shoe
- Several small growths clustered together
- A lesion that returns after home treatment
The tiny dark dots sometimes visible within a wart are small blood vessels. They are not seeds and do not mean the wart has roots.
Pressure may cause a layer of hard skin to form over the wart. This can hide its surface and make it difficult to distinguish from a corn without an examination.
When to Seek Professional Treatment
Schedule an appointment if:
- The growth is painful
- It begins spreading
- Several warts develop
- It bleeds or changes in appearance
- Home treatment has not worked
- It repeatedly returns
- You are unsure whether it is a wart
- The growth affects your walking
- You have diabetes or poor circulation
- You have reduced sensation or a weakened immune system
Do not cut, shave, burn, or dig into a suspected wart. This can cause bleeding, infection, scarring, and spread of the virus.
Patients with diabetes, circulation problems, or reduced sensation should avoid over-the-counter wart-removal products unless directed by a healthcare professional.
How Plantar Warts Are Diagnosed
A podiatrist can often identify a plantar wart by examining the growth. The evaluation also helps rule out corns, calluses, foreign bodies, cysts, and other skin lesions.
During your appointment, the podiatrist may:
- Examine the surface of the growth
- Check whether normal skin lines are interrupted
- Look for small blood vessels
- Determine whether side-to-side pressure causes pain
- Evaluate the location of the lesion
- Check for additional warts
- Examine surrounding skin
- Review previous treatments
- Evaluate circulation and sensation
- Ask about changes in size, color, or shape
The podiatrist may carefully reduce a small amount of thickened surface skin to examine the area more clearly.
If the appearance is unusual or the diagnosis remains uncertain, a small tissue sample may be recommended. This helps rule out another type of skin growth.
Plantar Wart Treatment Options
Treatment depends on the number, location, depth, and size of the warts. Your age, medical history, immune status, and previous treatment results may also affect the recommendation.
Plantar warts can be difficult to eliminate, and more than one treatment session may be required.
Professional Reduction
The podiatrist may carefully remove thickened skin covering the wart. This reduces pressure and allows the affected tissue to be treated more directly.
Professional reduction may improve comfort, but it is not usually enough to eliminate the viral infection by itself.
Topical Medication
Prescription-strength medication may be applied to gradually remove infected skin. Treatment may require repeated applications over several weeks.
The surrounding healthy skin should be protected, and the medication should be used according to the instructions provided.
Cryotherapy
Cryotherapy uses controlled freezing to damage wart tissue. The treated area may become tender or form a blister as it heals.
More than one treatment session may be necessary, particularly for deeper or larger plantar warts.
Swift Microwave Therapy
Swift microwave therapy delivers controlled microwave energy into the affected tissue. The treatment is designed to stimulate an immune response against the virus responsible for the wart.
The number of sessions needed varies, and results are not immediate. The treated wart may gradually reduce as the immune system responds.
Swift is not appropriate for every patient. The podiatrist will review your health history and evaluate the wart before recommending treatment.
Other In-Office Treatments
Depending on the condition, other treatments may be considered to remove infected tissue or stimulate an immune response.
The podiatrist will explain the potential benefits, expected healing, and number of visits associated with the recommended option.
Surgical Removal
Surgical removal may be considered for selected warts that remain painful or do not respond to other treatments.
Because surgery can leave a scar on a weight-bearing area, the benefits and potential risks should be carefully considered. Surgery is not usually the first treatment option.
Preventing Plantar Warts From Spreading
Plantar warts can spread to other areas of the foot and to other people. Preventive measures may reduce exposure and limit transmission.
Helpful precautions include:
- Wear sandals in communal showers
- Avoid walking barefoot in locker rooms
- Keep the feet clean and dry
- Change damp socks
- Avoid touching or picking at the wart
- Cover the wart when directed
- Wash your hands after touching the affected area
- Do not share shoes, socks, or towels
- Do not share nail clippers or foot-care tools
- Use separate instruments for affected skin
- Avoid shaving over the wart
- Clean surfaces that contact bare feet
- Follow the full treatment plan
Avoid repeatedly checking or trimming the wart yourself. Manipulating the area may cause bleeding and spread viral particles to nearby skin.
Frequently Asked Questions About Plantar Warts
Are plantar warts contagious?
Yes. The virus can spread through direct contact or contaminated surfaces. However, not everyone exposed to the virus will develop a wart.
How can I tell a plantar wart from a corn?
A plantar wart may interrupt normal skin lines and contain tiny dark dots. A corn usually develops over a pressure point and has a concentrated core. A podiatrist can confirm the diagnosis.
Can a plantar wart go away without treatment?
Some plantar warts eventually resolve when the immune system clears the virus. However, this may take a long time, and the wart may become painful or spread while waiting.
Should I cut out a plantar wart?
No. Cutting or digging into a wart can cause bleeding, infection, scarring, and viral spread. Professional treatment is safer.
Why does my plantar wart keep returning?
The wart may return if infected tissue remains or the immune system has not fully controlled the virus. Reinfection or spread from another untreated wart is also possible.
Is Swift treatment painful?
Patients may feel brief warmth or discomfort while energy is delivered. The experience varies depending on the size, depth, and location of the wart.
When should someone with diabetes seek treatment?
A person with diabetes should have any new foot growth professionally evaluated. Do not use acid treatments or attempt to remove a suspected wart at home.
