Plantar Warts

Plantar warts are a type of skin infection caused by the human papillomavirus (HPV). They appear on the sole or bottom of the foot and can be painful. Plantar warts are common and can affect anyone, but they are more prevalent in children and young adults.

Causes and Risk Factors

Plantar warts are caused by the HPV virus, which enters the body through small cuts or cracks in the skin. The virus thrives in warm, moist environments, making areas around swimming pools, locker rooms, and showers common places for infection to occur. People with weakened immune systems are more susceptible to plantar warts.

Symptoms

The symptoms of plantar warts include:

• A small, rough growth on the sole or bottom of the foot
• Pain or tenderness when walking or applying pressure to the area
• Black dots in the center of the wart, which are actually small blood vessels
• A thickening of the skin around the wart

Diagnosis

A doctor can diagnose plantar warts by visually examining the foot and taking a medical history. In some cases, a biopsy may be performed to rule out other conditions.

Treatment Options

Treatment options for plantar warts include:

• Cryotherapy: freezing the wart with liquid nitrogen
• Salicylic acid: applying a topical solution to dissolve the wart
• Cantharidin: applying a blistering agent to the wart
• Surgical removal: cutting out the wart
• Laser therapy: using a laser to destroy the wart

Prevention

To prevent plantar warts, it is recommended to:

• Wear shoes or sandals in public areas, especially around swimming pools and locker rooms
• Keep the feet clean and dry
• Avoid sharing personal care items, such as towels and razors
• Get vaccinated against HPV, if recommended by a doctor

Complications

If left untreated, plantar warts can lead to complications, such as:

• Persistent pain or discomfort
• Spread of the virus to other parts of the body
• Development of secondary infections, such as bacterial or fungal infections
