Plantar warts may be small in size, but they can be a big nuisance. Since they grow inward, they cause pain and discomfort whenever you step on the part of the foot where they are positioned. There are some at-home remedies you can try, and there are also over-the-counter treatments sold at most pharmacies. However, these solutions have limited effectiveness. If you want to get rid of plantar warts right away, you should see a podiatrist.
