I have a plantar wart on my left foot toward the center. It has black dots on it and it is yellow and pretty hard. I have tried to use Dr. Scholls on it which I completely followed the directions to but it just doesn't work. I also have tried to use the duct tape and bandage methods which worked on a wart that I had on my finger but it somehow doesn't work on my foot wart. I am a swimmer and I don't know what to do or how to get rid of it and I don't know if I should see a doctor since it could be expensive. It has been really painful lately and causing my whole foot to be very itchy. What should I do to cure it?
