If you suspect that you may have a staph infection, it's best to get to a doctor. This strain is treatable if caught early, but can be fatal so it's nothing to sneeze at. I went online earlier to look for images of a staph infection and there was quite a variation. The one main component is that there is an open wound that allows the infection to take hold. If you have a cut or abrasion treat it with an antibiotic ointment and cover with a bandaid.
