Almost everybody carries MRSA (Form of Staff Infection) but it stays dormant in your blood stream.  But when  it does come out it starts as things like body cramps and acne. I wouldn't freak out over a pimple, could just be a pimple. Don't believe what you here on TV or internet either just because MRSA happens to be highly resistant to some antibiotics it isn't to all so it's not what it's hyped up to be. Just get tested and if it's active they will put you on antibiotics.
