Have you noticed a rough patch of skin on the bottom of your foot that’s causing discomfort or pain while walking? It might not be just a callus. You could be dealing with a plantar wart—a common but often misunderstood condition caused by a viral infection. In this post, we’ll walk you through the plantar wart symptoms, what causes them, and how you can treat them effectively.
A plantar wart is a small growth that typically appears on the soles (plantar surface) of your feet. It’s caused by the human papillomavirus (HPV) entering the skin through small cuts or cracks. Unlike other warts, plantar warts are subjected to pressure from walking and standing, which can cause them to grow inward, making them more painful and harder to identify.
Recognizing the symptoms early can help prevent the spread and make treatment easier. Here are the most common plantar wart symptoms:
Plantar warts often look like small, rough, grainy bumps that may be flesh-colored, brown, or gray.
These are tiny clotted blood vessels and are sometimes referred to as “wart seeds.” They’re a hallmark feature of plantar warts.
Due to pressure from walking, plantar warts are often covered by a layer of thick, hard skin (similar to a callus).
Because the wart grows inward, it can press against the nerves in your foot, leading to discomfort or sharp pain when standing or walking.
Normal skin has clear, continuous lines. A plantar wart interrupts this pattern with its rough texture and border.
Plantar warts are caused by certain strains of HPV, which thrive in warm, moist environments. Common ways people contract the virus include:
Not everyone who comes into contact with HPV will develop a wart—your immune system plays a significant role.
Anyone can develop a plantar wart, but you’re more at risk if you:
If you suspect a plantar wart and it’s not going away, or it’s causing pain, it’s time to see a foot specialist. You should also seek treatment if:
At the Foot and Ankle Center of Arizona, we provide expert diagnosis and treatment for all types of foot conditions, including plantar warts.
There are several ways to treat plantar warts depending on severity and response to initial care. These include:
Salicylic acid patches or gels can gradually remove layers of the wart, but may take weeks or months to be effective.
Freezing the wart with liquid nitrogen can destroy wart tissue, though multiple treatments may be needed.
Pulsed dye lasers can target the blood vessels feeding the wart, leading to its eventual destruction.
For stubborn or painful plantar warts, a podiatrist may remove them under local anesthesia.
Used in resistant cases, this treatment stimulates the immune system to fight off the virus causing the wart.
While there’s no guaranteed way to avoid HPV entirely, you can take these steps to reduce your risk of developing plantar warts:
It’s easy to confuse plantar wart symptoms with corns, calluses, or even foreign bodies lodged in the skin. A podiatrist can distinguish between these and recommend the most effective treatment, especially when home care doesn’t work.
Plantar warts may be small, but the pain and inconvenience they cause can be significant—especially if left untreated. Recognizing the early plantar wart symptoms like black dots, thickened skin, and tenderness can help you take prompt action. Whether you’re dealing with one persistent wart or several, professional care is often the most effective route to recovery.

Q: Are plantar warts contagious?
A: Yes, they can spread through direct contact with infected surfaces or skin.
Q: How long do plantar warts last?
A: Without treatment, they can last months or even years. Early treatment speeds up recovery.
Q: Can I remove plantar warts at home?
A: Over-the-counter options may work for mild cases, but persistent or painful warts should be treated by a specialist.
Q: Will plantar warts go away on their own?
A: Sometimes they do, especially in children, but many cases require medical intervention.
Plantar warts are caused by the human papillomavirus (HPV) and commonly appear on the soles of the feet. Key plantar wart symptoms include rough, grainy skin, black dots (clotted blood vessels), thickened callus-like skin, and pain while walking. They spread through contact with contaminated surfaces like public showers or locker rooms. High-risk groups include children, athletes, and those with weakened immune systems. Treatments range from over-the-counter solutions to cryotherapy, laser therapy, and surgical removal. Early diagnosis and professional care are vital for effective relief. Visit Dr. Kris A.
