Inside are small, clotted blood vessels that resemble black splinters. They can grow anywhere on your body, but most likely will appear on the bottoms of your feet or the palms of your hands. Some warts will disappear naturally, but more often than not, they spread. What most people don't understand is if you have a cut or break in your skin and come in contact with the wart virus you can get warts. To help avoid getting warts on your feet, we always suggest that people wear some sort of shoe or sandal in public places.
Most warts are usually painless.
Since feet bear all your weight, warts grow inward, making them difficult to treat. The best way to treat warts is to apply salicylic acid directly on them. Most drugstores carry an over-the counter product. But Bruce warns the acid may cause soreness if not used carefully. If the warts do not respond to commercial medication, Bruce suggests seeing a dermatologist.
