I just noticed a bunch of tiny white bumps on my top lip. They are white, not clear, about the size of a pin point, and don't seem like they will erupt.
They are lined along the lip, right at the border of inside and outside, with more on the inner, wetter part, but some on the outer lip as well.
There are none on the lower lip.
There's no itching, maybe a slight burning, as if I have chapped lips.
Normally I probably wouldn't be very concerned, but my son has had recurring bouts of impetigo. It always seems to start with chapped lips, then the corners of his mouth, then beyond. He exacerbates it by dragging / wiping his sleeve across his mouth and cheek(s). He's had oral and topical prescriptions. He's at school, but when he gets home I'll check / ask if his "chapped" lips look(ed) like bumps.
Does this sound like the onset of impetigo, or, alternately, an underlying condition that could spread and become infected with impetigo-causing bacteria?
