I have the exact same problem!! I've gotten these pimples, mostly one at a time, but sometimes two, in the same places over and over again. I get them mostly when I've been studying for a long time for college.
They're more painful
than regular pimples and they itch. I was tested for herpes too, and the results were negative. No one seems to know what this is!
I tried using Mupirocin, an antibiotic, for about 4 days, but it didn't do a thing.
Did you come up with any helpful cures?
