The Facts on Common & Plantar Warts:
What Are Warts?
Warts are a skin condition identified as abnormal skin growths. Warts may appear as a bump with a rough surface, or it may be flat and smooth. Classic warts have somewhat of a cauliflower appearance to them. Tiny blood vessels grow into the wart and may appear as dark dots in the center. Typically, the skin lines and creases over the wart are distorted. Warts can appear either alone or in groups. While warts can be unsightly, some warts, such as plantar warts, can also be quite painful and can prevent you from moving comfortably.
There are two types of warts you’re most likely to experience:
Common warts usually occur on your fingers or hands. They are usually about the size of a pencil eraser and usually painless (but may be painful when touched). They can look and feel:
- Like a cauliflower on the surface: small, fleshy, or grainy bumps
- Flesh-coloured, pink, tan, or white
- Rough to the touch
- Sprinkled with black pinpoints or seeds (small, clotted blood vessels)
Plantar warts usually occur on the bottom of your foot. They may be solitary (a single wart) or mosaic (grow in clusters). They can be as large as two inches across but are typically about the size of a pencil eraser. They are commonly painful or tender when standing or walking, like there’s a stone in your shoe. They can look and feel:
- Like small, fleshy or grainy, rough growths on the bottom of your foot
- Like a well-defined spot under a layer of thickened skin (callus)
- Like clusters of small black pinpoints or seeds
- A mass that interrupts the normal lines and ridges of your foot
What Are Warts Caused By?
Warts can be caused by any of 100 or more types of human papilloma viruses (also called HPV), that enter the skin through a cut or abrasion. The virus causes the top layer of skin to grow rapidly, resulting in a wart.
The types of HPV virus that causes warts is contagious, and you can get it through direct contact from sharing personal items such as towels and razors, for example. You can even re-infect yourself by touching the wart and then another part of your body. Plantar warts often spread through warm, moist environments, like public showers and locker rooms where you walk around barefoot.
HOW TO HELP PREVENT WARTS?
Most warts are harmless and may even go away on their own without treatment, but they can be embarrassing and you may want to treat them if they are bothersome or painful. You’ll be happy to know there are some simple tips that can help you learn how to prevent warts:
- Avoid direct contact with warts and don’t pick at your own warts
- Wash your hands regularly, especially if you’ve been in contact with someone with warts
- Practice good hygiene in public places like wearing flip-flops or shower shoes in public pools, showers or gyms
- Keep warts from spreading by covering them with a bandage
- Skin cuts and abrasions can make it easier for the virus to enter your body: clean and cover cuts and scrapes, avoid nail biting, and prevent dry and cracked skin
- Change your shoes daily, and keep your feet clean and dry
- Use a disposable emery board, and don’t use the same emery board, pumice stone, or clippers on your warts as you do on your healthy skin and nail
HOW TO GET RID OF WARTS?
There are a number of ways you can treat and remove warts on your own, or with the help of your doctor:
- Nonprescription wart treatments: Over-the-counter products that contain salicylic acid can be used to treat plantar warts, along with the regular use of a pumice stone and good foot hygiene. It may take several weeks for them to go away completely. Try Dr. Scholl’s ClearAway® Wart Removers, including solutions designed for common wart removal and plantar wart removal.
- Freezing (also called cryotherapy): Your doctor could treat your warts by applying liquid nitrogen to freeze them. This causes a blister to form around your wart, and eventually the dead tissue (including the wart) falls off. The application of liquid nitrogen can be painful, so your doctor may apply a numbing agent. Cryotherapy can be combined with salicylic acid treatments. There are also nonprescription cryotherapy products available over-the-counter, such as Dr. Scholl’s FreezeAway® Wart Removers.
You should see a doctor about your warts if:
- They’re painful and interfere with your activities or change in appearance or colour
- You’ve tried to treat them yourself, but they don’t go away or keep coming back
- You have a weakened immune system, for any reason
- You aren’t sure if they’re actually warts
