Cryosurgery for Warts: What It Is and Why It Works

If you’ve noticed a small, rough bump on the bottom of your foot or between your toes that won’t go away, chances are it’s a wart—and not just any wart, but a plantar wart, the kind that can make walking feel like you’ve got a pebble in your shoe 24/7. These stubborn skin growths are caused by a virus and are notorious for sticking around, even after trying over-the-counter remedies. That’s where cryosurgery comes in.

At Step Ahead Podiatry in Edmonton, we treat plantar warts using professional methods that go beyond what drugstore treatments can do. One of the most effective options is cryosurgery, a precise and minimally invasive technique that freezes the wart at its core—destroying the virus and helping you get back to walking comfortably again.

Key Takeaways

• Plantar warts are caused by the human papillomavirus (HPV) and commonly affect the soles of the feet.

• Cryosurgery uses liquid nitrogen to freeze the wart, destroying infected tissue.

• It’s a quick, in-office procedure that requires minimal downtime.

• Cryosurgery is often more effective than over-the-counter wart treatments.

• Step Ahead Podiatry provides safe, professional wart removal for patients in Edmonton.

What Is a Plantar Wart?

Warts are small skin growths caused by certain strains of the human papillomavirus (HPV). Plantar warts specifically occur on the bottom of the feet, often on weight-bearing areas like the heel or ball of the foot. This pressure can cause the wart to grow inward, sometimes creating a painful, callus-like feel.

Common symptoms of plantar warts include:

• A rough, grainy lesion on the sole of the foot

• A hard callus over a well-defined spot

• Black dots (clotted blood vessels) in the center

• Pain when standing or walking

Plantar warts can be highly persistent, especially if not treated correctly or caught early.

Why Over-the-Counter Wart Treatments Often Fail

It’s normal to try treating a wart at home first. After all, drugstores carry a range of salicylic acid solutions, medicated pads, and freeze sprays. But here’s the issue: many of these treatments simply aren’t strong enough to reach the virus where it lives—deep in the layers of your skin.

Limitations of OTC Wart Treatments:

• Weak freezing agents: Drugstore freeze sprays don’t get cold enough to destroy the entire wart.

• Inconsistent application: Applying creams or gels at home can miss the core of the wart.

• No professional debridement: Dead skin builds up and blocks treatments from penetrating effectively.

• No guidance: Without proper diagnosis, you might be treating a corn, callus, or even a different condition altogether.

At Step Ahead Podiatry, we often see patients after months—or even years—of failed home treatments. Professional care makes all the difference, especially with cryosurgery.

What Is Cryosurgery for Warts?

Cryosurgery, also known as cryotherapy, is a medical procedure that uses liquid nitrogen to freeze and destroy abnormal tissue. In the case of plantar warts, this means freezing the virus-infected cells, causing them to die and eventually fall away as the skin heals.

The intense cold from the liquid nitrogen forms a blister around the wart. This separates the wart from the healthy skin underneath and prompts your body to build new, healthy skin cells in its place.

What to Expect During a Cryosurgery Appointment

At Step Ahead Podiatry, your comfort and safety are our priorities. Here’s what you can expect from start to finish:

1. Initial Assessment

We begin by examining your foot to confirm that the lesion is indeed a wart. We'll look at the shape, depth, and number of lesions, and evaluate how long you've had them.

2. Prepping the Area

Before freezing the wart, we’ll often debride (shave down) the top layer of skin. This allows the cryospray to penetrate more effectively and target the virus directly.

3. Application of Liquid Nitrogen

Using a controlled spray device, your podiatrist will apply liquid nitrogen directly to the wart. The spray feels cold—sometimes stingingly so—but the treatment usually lasts only 10–30 seconds per lesion.

4. Aftercare and Follow-Up

You may develop a blister or scab over the treated area in the following days. This is normal and means the wart tissue is separating. Most patients return for repeat treatments every 1–3 weeks, depending on the wart’s size and how your body responds.

Is Cryosurgery Painful?

It can be uncomfortable, but most patients tolerate it well. The freezing sensation only lasts a few seconds. Some people describe a sharp, cold sting, while others feel pressure or mild aching afterward. If you’re especially sensitive, we can discuss using a topical numbing agent beforehand.

After the procedure, the area may feel sore for a day or two—especially if the wart was in a weight-bearing area. Wearing cushioned footwear or applying a bandage can help ease discomfort.

How Many Treatments Will I Need?

Most plantar warts require multiple sessions of cryotherapy to fully resolve. On average, patients need 3 to 5 treatments, spaced about a week or two apart. However, deeper or larger warts may take longer.

The number of treatments can vary based on:

• How long you’ve had the wart

• Whether it’s a single wart or multiple (cluster)

• Your immune response

• Prior treatments attempted

At Step Ahead Podiatry, we’ll monitor your progress and adjust your treatment plan as needed to ensure the best results.

Benefits of Cryosurgery for Warts

Cryosurgery is one of the most effective in-clinic wart removal options available—and here’s why so many Edmonton patients choose it:

• Fast procedure – Treatments typically take less than 15 minutes

• Non-invasive – No cutting or stitching required

• Minimal downtime – You can usually resume normal activities right away

• Safe and targeted – Precise application reduces damage to surrounding tissue

• High success rate – Especially when compared to home remedies or weaker freeze kits

When Cryosurgery Works Best

Cryosurgery is especially effective when:

• The wart has not responded to OTC treatments

• The wart is newer or smaller

• The patient has a healthy immune system

• You want to avoid surgical excision or prescription medication

It’s also a great option for kids and teens who may not be ready for more invasive procedures but need something stronger than store-bought treatments.

Tips for a Smooth Recovery

After cryosurgery, it’s important to follow a few simple aftercare tips to help the skin heal and avoid reinfection:

• Keep the area clean and dry

• Avoid picking at scabs or blisters

• Wear well-cushioned shoes if the wart was on a weight-bearing spot

• Use a bandage or pad to reduce friction

• Wash your hands thoroughly after touching the area

If prescribed, we may also suggest a topical solution to apply between sessions to enhance treatment success.

Preventing Future Warts

Warts are caused by a virus, which means they can be spread from surface to skin—and even from one part of your foot to another. After treatment, it’s important to reduce your risk of recurrence:

• Don’t go barefoot in public showers, gyms, or pools

• Avoid sharing socks, shoes, or towels

• Disinfect shoes and keep feet dry

• Use flip-flops in communal locker rooms or bathrooms

• Address foot injuries promptly, as broken skin can invite HPV

If you have recurring plantar warts, we may also discuss immune support or additional therapies to reduce your chances of reinfection.
