If i pop this bump and liquid comes out and touch another part of my face it spreads there. Some will start out looking like a small blister but a little red and once I pop it and touch anothe part of my body i will get one there. They have been on my chest, back,feet, and hands. I have even hard a culture done and the results showed no staph, and there was nothing growing on the culture. I have been on bactrim and I still get them. Please Help!!
