The abscess' are not big. The bigger ones were maybe 3 millimeters or so, and most were smaller. They are a white head (pus I presume), and red inflammation up to 1 cm in diameter around the head of the 'pimple'. The first time I got a big painful one, the Dr gave me Mupirocin cream which I have since used quite a few times on subsequent abscess'.
I asked the doctor once to take a culture, but he said it was too small.
