I found tube of Bactroban
that my ex-girlfriend left behind (which had never been opened - must have been a spare tube or something). The doctor had prescribed it to her when she got a rash on her skin and it worked really great.
Anyway, I gave it a shot. I used it for about a week steady (twice a day) and combined that with taking some oil of oregano pills (which are supposed to be good for digestion, etc). I also used a few drops of tea tree oil under my tongue.
