Having had the MRSA infection 3 times in 3 years, I have had a sample of what you are going through, though not as serious as the condition you have currently. What seems to have worked for me, to keep from getting this nasty bug again, is to use a quaternary ammonia detergent added to my regular laundry detergent, and bathing with Hibiclens. Hope you get rid of the current situation and hope it NEVER RETURNS!
