red pimple with white puss filled center on bottom of foot

I have a red pimple with white puss filled center on the bottom of my foot in the arch of my foot.  I've had it for a few weeks, and it hurts. It doesn't get very big, but when it becomes very tender and pops, it becomes like peeling skin that then drys up and turns dark in color.  The problem is that when one drys up, another one appears almost immediately.  What do you think it is?  I don't like sitting in doctors offices for a whole day just to get a simple answer, when it is possible that I can just by an over the counter topical medication for it to go away. Please someone, if you have any advise or a similar problem, please let me know.

I also have exactly the same thing.  I did got to the doctor when it first happened and he said it was an allergic reaction to something.  A year later, and still only affecting one foot I am not sure...
