With a high intensity beam of light, many skin conditions can be treated safely and efficiently. When this procedure is appropriate, there is improved healing, less discomfort and fewer possible complications.
What are Plantar Warts?
Warts are one of several lesser afflictions of the foot, which nevertheless can be quite painful. They are caused by a virus, which typically invades the skin through small cuts and abrasions. They are frequently called plantar warts, because they appear most often on the plantar surface, or sole, of the foot. They can appear anywhere on the skin, however, and technically only those on the sole are properly called plantar warts.
Children, especially teenagers, tend to be more susceptible to warts than adults; some people seem to be immune, and never get them.
Most warts are harmless and benign, even though painful. They are often mistaken for corns, which are layers of dead skin that build up to protect an area which is being continuously irritated, whereas a wart is a viral infection.
It is also possible that a variety of other more serious lesions, including carcinomas and melanomas, although they are not overly common, can be mistakenly identified as warts. Because of those identification problems, and for pain relief, itÃs wise to consult a podiatrist about any suspicious growth or eruption on the skin of the feet.
On the bottom of the feet, plantar warts tend to be hard and flat, rough-surfaced, with well-defined boundaries; they are generally fleshier when theyÃre on the top of the feet or the toes. They are often gray or brown (but the color may vary), with a center that appears as one or more pinpoints of black.
Source of the Virus
The plantar wart is often contracted by walking barefooted on dirty surfaces or littered ground where the virus is lurking. The virus is also sustained by warm, moist environments, so that warts are often associated with communal bathing facilities -- more for the wet surfaces, however, rather than for transmission in water, which probably is rare.
If left untreated, warts can grow to an inch or more in circumference, and they can spread into clusters of several warts. Like any other infectious lesion, they are spread by touching and scratching, and even by contact with skin shed from another wart. They may also bleed, another route for spreading.
Warts can last for varying lengths of time, which may average about 18 months. Occasionally, they spontaneously disappear after a short time. Perhaps just as frequently, they can recur in the same location.
When plantar warts develop on the weight-bearing areas of the feet -- the ball of the foot, or the heel, for example -- they can be the source of very sharp, burning pain. Pain occurs when weight is brought to bear directly on the wart, although pressure on the side of a wart can create pain just as intense.
Tips for Prevention
• Avoid walking barefooted, except on sandy beaches
• Change shoes daily
• Keep feet clean and dry
• Check children's feet periodically
• Avoid direct contact with warts -- from other persons, and from other parts of the body
• Do not ignore skin growths or changes in your skin
• Visit your podiatrist as part of your annual health check-up
Self treatment is generally not advisable. Over-the-counter preparations contain chemicals that destroy skin cells, and it takes an expert to destroy abnormal skin cells (warts) without also destroying surrounding healthy tissue. Self treatment with such medications especially should be avoided by diabetics and those with cardiovascular or other circulatory disorders, which cause insensitive feet. Never use them in the presence of an active infection.
It is possible that your podiatrist will wish to prescribe and supervise your use of a wart-removal preparation. More likely, however, removal of warts by a simple surgical procedure will be indicated.
One common way is by use of a carbon dioxide laser unit. The affected area is anesthetized and the lesion is removed with a beam of light.
With laser surgery, the wart is vaporized, using focused light energy produced by a laser. To lessen pain, a local anesthetic is often used with this procedure
Such surgical procedures are sometimes used in combinations, as well. Local anesthetics may be required.
