Plantar warts develop on the bottom of your feet. These are benign growths caused by direct contact with human papillomavirus (HPV). These warts cause pain with pressure which can be described as sharp or burning. It usually starts as a single wart but can grow into a cluster. Plantar warts appear as thick, scaly, hard (callus-like), with tiny black dots (clogged blood vessels feeding the wart). You should avoid picking at the warts as this can spread to other parts of the foot, walking barefoot in public areas such as swimming pools and showers. You should change your shoes and socks daily, keep feet clean and dry.
It is time to come and see your foot doctor either if the wart starts to multiply, if any changes to color or shape is noticed, if the pain/discomfort is interfering with activities. Also, if you are not sure if a growth on your foot is a wart you should have it examined to determine what it is.
