The diagnosis of plantar warts (on the bottom of the foot) or warts elsewhere is often not too difficult.  The most common signs and symptoms of warts include:
  • Thickening of the Skin:  Warts, especially plantar warts due to the repetitive stress of walking, often resemble calluses and have thick, hard skin.
  • Pain:  Warts are often painful, especially with pressure or when sides of warts are squeezed.  This is especially problematic with plantar warts, as they cause pain during walking or standing.
  • Black Dots:  Often you will hear people say "seed warts" or "my wart has seeds".  These small black dots seen in the thick tissue making up a wart are the most important feature to diagnosis a wart.   These black dots are capillaries (small blood vessels) in the skin that supply the wart.   When the top of the wart is removed, little areas bleed (often called "pin-point bleeding") and confirms the diagnosis.
