From past 2-3 months I have a small patch of corn like growth on the side of tips of the second and third finger of the right foot. I also have a corn on the thumb of foot. I tried to rip the corn on thumb through nail cutter. This helped the corn more or less. But after sometime a small patch of wart like patch appeared on next two fingers. They also have black dots in them. I tried to rip them with nail cutter twice but it grew back to it's later state soon after. Please suggest suitable course of action to get rid of the problem.
