Re: mrsa or recurring staph?
You can become colonised by staph, which can cause recurent infections.
If this is the case, the way to decolonise your self is
Use Hibiclens in the shower every day for a 10 days instead of soap and shampoo - be especialy thorough around the ano-genital region and armpits, then use a washcloth to lather up the entire body, including the scalp.
Apply some Neosporin into both noistrils twice a day for 10 days using a qtip, spear it around, and press the nostrils together
Of course, this needs discussing with your doctor.
However, 2 staph infections 6 months apart dont nessecerily mean you are colonised, it could just be bad luck
