Warts and Lesions
Warts are one of several soft tissue conditions of the foot that can be quite painful. Like any other infectious lesion, plantar warts are spread by touching, scratching, or contacting skin shed from another wart.
Spreading
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.
Types of Warts
Warts are generally raised and fleshier when they appear on the top of the foot or on the toes, but plantar warts tend to be hard and flat, with a rough surface and well-defined boundaries.
Walking Barefoot
Warts are often contracted by walking barefoot on dirty surfaces where the virus is lurking.
