I am currently dealing with a somewhat similar problem after a course of Antibiotics .
I'm currently treating by going on the GAPS diet to heal the gut, doing daily water/coffee enemas, taking probiotics (biokult and threelac) and basic supplements (mag/calcium, B complex, vit C, vit E, cod liver oil). I also found that it was important to let the skin remain dry until it healed itself. Water just softened the tissue and exacerbated the issue.
This seems to be working as I haven't had an outbreak on my face in over a week. I had it insanely bad all over my arms/top of my hand and some on my face as well. I attributed it to my body releasing toxins through my skin because my liver wasn't doing it fast enough. The enemas seem to be easing the herxheimer response.
