My daughter (13 years old) had a few MRSA outbreaks. I was surprised to hear that word come from the doctors mouth. It started a few months ago w/ what I thought was a clogged tear duct due to eyeliner. But when you pulled the eye down a bit you could see a big white oozie spot, we put hot compresses on it and it came to the top, came out and all the swelling went down. A few months later it started in the little crux of her ear, again we attributed to hair products but this time the spot swelled so badly it started to close the ear off and her glands swelled in her face and neck. IT happened so quickly it was only about a day or two when it started to look really bad. We did the hot compress thing, planning on taking her to the doctor the next day and tons of stuff came out...you could see a yellow spot surrounded by white. We took her to the doc and by simply their touch, more stuff came out and they put her on Clyndimicin for 10 days, which totally killed her stomach. But the infection went away the glands came down immediately. The next time was after she had a nasty cut/bruise from a soccer game on her shin..(even w/ the shin guards). The spot swelled but I didn't think anything of it, no real boil looking thingy and I just figured that was a bad spot to have a open cut from a cleat. It took a while to heal but in the meantime and right before we went to Aruba, she tripped and hit the corner of her mouth on (get this) the corner of the cable box. This is why we say "don't run in the house". No open sore, just she bit her lip on the inside and had a small bruise in the corner of her mouth. She wears braces so I figured it would be irritating to the inside of her mouth. After a couple of days the bruise started to get hard and like a pimple so I took her to the doc and sure enough back on the same antibiotic for 3 weeks this time, 3 times a day. The doc explained that in many people the infection lives in their nose and it makes them high risk for this infection and to put bactrum on a q-tip and rim the nostril. So when there is some sort of trama on her now we watch for signs like swollen glands etc. She is not one to have teen break outs either and I cleaned like a crazy person and always wash their sheets w/ bleach, the rest of us, including her two brothers and her team-mates and friends did not get any kind of infection from her. It was very weird and I'm def. on alert now and so is she.
I hope this helps, I'm glad things worked out w/ your daughter. Its weird how there is all of these crazy infections out there, even w/ the cleanest person/family I guess you never know.
