What it is
A common wart is a small, rough skin growth caused by a type of human papillomavirus (HPV). Warts often appear on the fingers, hands, and feet, and they can look different from person to person. Having one is common and nothing to be embarrassed about.
A callus is an area of thickened, hardened skin that forms as a protective response to repeated rubbing or pressure, such as from shoes, tools, or gripping. Calluses tend to be flat or evenly thickened rather than a distinct raised bump.
People often describe a few general differences. Warts may interrupt the normal lines of the skin's surface and may show tiny dark dots, while calluses usually keep the skin's natural lines. Pain can differ too, but looks can be misleading, and the two can even occur together. That is why an exam by a dermatologist, podiatrist, or primary care provider is the reliable way to know.
How it’s traditionally been approached
Because a callus is tied to friction and pressure, it has traditionally been approached by looking at what is causing the pressure, such as footwear fit or repeated hand use. Gentle care to soften thickened skin is a common approach, and a clinician can advise on what is appropriate for you.
Warts have traditionally been approached in several ways, including over-the-counter salicylic acid products, freezing (cryotherapy) in a clinic, and other in-office options chosen by a clinician. Some warts go away on their own over time, and some are slow to change. Results vary, and warts can return.
If you have diabetes, poor circulation, neuropathy, or a weakened immune system, ask a provider before treating any spot at home, especially on the feet. Never cut, burn, or dig out a growth at home. Over-the-counter wart products are not meant for the face or genital area.
How the right provider may help
A visit with a dermatologist, podiatrist, or primary care provider usually starts with questions about how long the spot has been there, whether it hurts, and whether it has changed. The clinician will look closely at the skin and may use a simple tool to examine it. This helps sort out whether it looks like a wart, a callus, or something else.
The right provider may help by identifying what the spot is and discussing options that fit your situation, which may include watchful waiting, home care, or in-office approaches. Whether any option is appropriate is something only a licensed clinician decides after an evaluation. No approach is guaranteed to work.
Helpful questions to ask include: What do you think this is? Could pressure or footwear be involved? What are my options, and what are the trade-offs? Is home care safe for me given my health history? What should I watch for, and when should I come back? You can find licensed providers through Providers.plus.
The whole-person view
Body, mind, and stress affect each other. A spot that is visible or uncomfortable can bring self-consciousness, worry, or frustration, and stress and overall health can in turn shape how we feel day to day. Looking at the whole person, including sleep, general health, and daily habits, is one way people think about well-being.
If worry about your skin or appearance is weighing on you, body-based support such as Somatic Experiences may help some people feel more at ease in their bodies. Talk therapy through Therapists.plus is another option for working through stress or embarrassment. These are supportive options, not substitutes for a skin exam.

Keep in mind
- Any spot, growth, mole, or 'wart' that is changing, bleeding, itching, irregular in shape or color, or not healing should be checked by a dermatologist for skin cancer, and should not be self-treated.
- The ABCDEs of melanoma (asymmetry, border, color, diameter, evolution) are only a general guide to why checks matter, not a way to diagnose yourself.
- Warts can return, results vary, and no treatment is guaranteed to cure warts or HPV or prevent recurrence. Ask a licensed clinician what is right for you.
- For emergencies call 911. If you are in crisis, call or text the 988 Lifeline.

Frequently asked questions
What is the difference between a wart and a callus?
A wart is a skin growth caused by a virus (HPV), while a callus is thickened skin that forms from repeated pressure or friction. They can look alike, and sometimes occur together. A licensed clinician can tell which one you have with an exam.
How can I tell if it's a wart vs callus at home?
You can't be certain at home, because they can look very similar. Some people notice that warts may disrupt the skin's normal lines or show tiny dark dots, while calluses usually keep those lines. A dermatologist, podiatrist, or primary care provider can give a reliable answer.
Is a wart vs callus on the foot treated the same way?
Not necessarily. A callus is often approached by addressing pressure or friction, while a wart is approached as a virus-related growth. A clinician decides what is appropriate after an evaluation, especially for feet.
Are warts contagious but calluses are not?
Generally, yes. Warts are linked to a virus and can spread through skin contact or shared surfaces, while calluses come from pressure and are not contagious. Ask a provider about everyday steps to reduce spreading.
Can I use over-the-counter wart remover on a callus?
Please check with a provider first. Over-the-counter products are made for specific uses, and using them on the wrong kind of spot may irritate the skin. People with diabetes, poor circulation, neuropathy, or a weakened immune system should always ask a provider before home treatment.
When should I see a doctor about a spot that might be a wart or callus?
See a dermatologist if a spot is changing, bleeding, itching, irregular in shape or color, painful, or not healing, since skin cancer needs to be ruled out. It is also wise to be seen if you are unsure what it is or have diabetes or circulation concerns. Do not cut or burn it at home.
