"&amp;lt;p&amp;gt;Warts on the feet, also known as plantar verruca, can often look like callouses. But there are a few distinguishing features warts have that callouses do not. First, warts will interrupt the skin lines on the bottom of the foot, whereas callouses will have skin lines go through the hard, dead skin. Second, warts usually have small black dots, which are the blood supply to the warts. Callouses do not have black dots (unless your feet are dirty). Lastly, warts are more painful when they are squeezed side to side and callouses are more painful when pushed on directly. If you&amp;amp;#39;re coping with warts on your feet, &amp;lt;a href=&amp;quot;https://www.verywell.com/what-are-plantar-warts-1337762&amp;quot; data-component=&amp;quot;link&amp;quot; data-source=&amp;quot;inlineLink&amp;quot; data-type=&amp;quot;internalLink&amp;quot; data-ordinal=&amp;quot;1&amp;quot;&amp;gt;this article on plantar warts&amp;lt;/a&amp;gt; will answer many of your questions.&amp;lt;/p&amp;gt;&amp;lt;p&amp;gt;The little black dots near the center of the wart are the blood supply to the wart.&amp;lt;/p&amp;gt;&amp;lt;p&amp;gt;Warts are caused by a virus, and once the virus invades the body, multiple warts can develop.&amp;lt;/p&amp;gt;&amp;lt;p&amp;gt;Squeezing warts from side to side is more painful than pressing directly on the wart.&amp;lt;/p&amp;gt;&amp;lt;p&amp;gt;Notice the well-defined warts that interrupt the natural skin lines. This characteristic helps to show the difference between a wart and a callous.&amp;lt;/p&amp;gt;"^^<http://www.w3.org/2001/XMLSchema#string>
