Warts are one of several soft tissue conditions of the foot that can be quite painful. a wart may be raised or if on the sole of the foot, the pressure of walking causes the wart to be pushed into the skin. Those that appear on the sole of the foot are called plantar warts. Verruca can appears as singular legions or in groups.
They are caused by a virus and can appear anywhere on the skin. Children, especially teenagers, tend to be more susceptible to warts than adults.
Verrucae are caused by the Human Pappilloma Virus (HPV) which induces the benign epithelial legions in the skin.
The HPV virus is contagious and generally invades the skin through small or invisible cuts and abrasions. The plantar wart is often contracted by walking barefoot on dirty surfaces or littered ground where the virus is lurking. The causative virus thrives in warm, moist environments, making infection a common occurrence in communal bathing facilities.
If left untreated, warts can grow to an inch or more in circumference and can spread into clusters of several warts; these are often called mosaic warts. Like any other infectious lesion, plantar warts are spread by touching, scratching, or even by contact with skin shed from another wart. The wart may also bleed, creating another route for spreading. Occasionally, warts can spontaneously disappear after a short time, and, just as frequently, they can recur in the same location.
Most warts are harmless, even though they may be painful. They are often mistaken for corns or calluses, which are layers of dead skin that build up to protect an area which is being continuously irritated. The wart, however, is a viral infection.
Plantar warts tend to be hard and flat, with a rough surface and well-defined boundaries; warts are generally raised and fleshier when they appear on the top of the foot or on the toes. Plantar warts are often gray or brown (but the color may vary), with a center that appears as one or more pinpoints of black. It is important to note that warts can be very resistant to treatment and have a tendency to reoccur.
When plantar warts develop on the weight-bearing areas of the foot (the ball of the foot, or the heel, for example), they can be the source of 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 equally intense pain.
The lifespan of the HPV can be anywhere from 5 months to 5 years and the legion frequently spontaneously disappear. Often, however, treatment is commenced immediately.
Self-treatment is generally not advisable. Over-the-counter preparations contain acids or 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 people with diabetes and those with cardiovascular or circulatory disorders. Never use these medications in the presence of an active infection.
Treatments may include the application of creams or liquid nitrogen to destroy and remove the area of affected tssue. In severe cases surgical removal of the verruca may be required.
