Warts are a skin infection or skin bumps that are very common about 10 percent of teenagers have warts. Plantar warts are the skin infection that is on the base side of your foot. Not being careful when using a public shower or walking around the locker room in your bare feet after a workout increases the risk for developing plantar warts.
Cause and symptoms:
Contrary to popular belief you can't get warts from touching a toad. They are caused by a virus that enters the body through a break in the skin. This virus grows in warm, moist places, like the environment created in a locker room or in your shoes when your feet perspire and the moisture is trapped. Plantar warts spread to other areas of the foot, as they do they increase in size, and multiply.
Plantar warts can become very painful. The warts can be pushed flat by walking them through but they just grow into the skin giving you the same feeling like the one that you have when there's a stone in your shoe.
Plantar warts have a time period and they disappear by themselves. In some cases though, they become very painful and thus you should seek treatment. Your dermatologist or physician may trim the wart and apply a chemically treated dressing. They may also give Salicylic acid patches, applied on a daily basis, and good foot hygiene, however even after treatment the wart might take several weeks before disappearing completely.
The best way of prevention is taking good care of your personnel hygiene especially your foot hygiene. Wearing a fresh pair of socks and applying powder can help.
