The wart often is painful but does not have to hurt. If you have plantar warts, I recommend going to see a doctor for care. They often spread and it is much easier to get rid of solitary wart. I know that there are over the counter methods, but they are best used under the active care of a podiatrist because it is easy to chemically burn the skin. I may remove the wart completely, or try and disrupt the blood supply to the wart.
Most people take their feet for granted.
Most people are not educated in proper foot care. Feet are out of sight and therefore out of people's mind. When summertime comes and people are barefoot or in sandals, then the number of people who present to the office increase because their feet are actually exposed to other people. I believe strongly that taking care of your feet is vital because if you cannot walk comfortably, it will affect all of your activities. Once I have educated my patients, they are more self-aware and will be more likely to take care of themselves.
