One day, you’re putting your socks on before heading out the door. You notice that there seems to be a spot on one of your toes that has a growth on it. It doesn’t hurt, so you don’t think much about it. A few days later, you’re at the doctor for your annual exam and show her your foot. She tells you that you have a plantar wart. How did this happen? Can you get rid of it? Is there a way to prevent it from coming back?
