Sorry to say it, but it ruined my life. I never went to the hospital, had 100% lung function, etc until I cultured MRSA in 2005. I started going in every six months, then less, until I spent three months a year inpatient, and the rest of the time on home IVs. I got a transplant in 2013, and now I'm not culturing it anymore; only pseudomonas. I think I acquired it at swim practice, but you never really know. Hope this helps.
