Common warts and plantar warts are both small, rough growths that occur on different areas of the body. They are usually accompanied by black pinpoints, which are small, clotted blood vessels that are better known as wart seeds. Both, common warts and plantar warts are caused by the human papillomavirus (HPV). This is an extremely common virus that has over 150 different types, but only a select few can cause warts on your hands or feet. The strands of HPV that cause common warts and plantar warts usually enter the body through tiny cuts or breaks in the skin. However, every immune system responds differently to the HPV virus, so not everyone who comes in contact with it will develop warts. In most cases, common warts and plantar warts are harmless and will typically go away on their own.
What is the difference between common warts and plantar warts?
The main difference between the two is location. Common warts occur most often on the fingers or hands and can sometimes appear grainy or fleshy. They are easily spread through skin-to-skin contact or by sharing objects, such as towels, nail files and nail clippers. Biting your nails can also warrant common warts to spread on the fingertips or nailbeds. Unlike common warts, plantar warts usually show up on the heels and balls of your feet because those areas bear the most pressure. This pressure can also cause the wart to grow inward under a thick, course layer of skin which can lead to pain and discomfort when walking or standing. Plantar warts are not highly contagious and do not spread easily from person to person. However, this strand of HPV does thrive in warm, wet environments so be extra careful walking around barefoot in locker rooms, swimming pools and gyms.
When should you see a doctor?
You should see a board-certified dermatologist if you experience any of the following:
- You are unsure if the growth is a wart.
- The growth is painful and interferes with daily activities.
- The growth is bleeding or changing in appearance.
- You have tried treating the warts, but they persist or spread.
- You have warts and are immunodeficient.
