question: Should I be overly concerned that I was told yesterday by the medical clinic I visited on Thursday evening that I am actually fhave a MRSA infection, not a regular Staph infection.   A week ago I went in for a few ingrown hairs in my left arm pit and one in my lower abdomen.  The largest on in my left arm pit was opened, drained, cleaned, and packed.On Thursday evening, I was given a prescription for Bactrim and told to take 1 pill 2 times a day.I went in again on Saturday for the packing to be removed and 2 was told it looked like it was doing well.  I was told the intentional lab results indicated it was Staph, but it would be cultured in the lab..Sunday evening the bump on my abdomen, which had been puffy and a bit red, started oozing and got pretty bloody.  There was also a dark pinkish oval on my skin around it.So I went to the only urgent care clinic open on Labor Day in our small town.  The PA I saw lanced it, cleaned, it and packed it.  He was concerned and thought it looked more like MRSA and was surprised this had happened as I had been taking Bactrim for 4 days.  So he recommended I start taking 2 pills, 2 times a day.  I went back on Wednesday to have the packing replaced.  Today I noticed the pink/red oval on my skin around the abscess on my lower abdomen.  Does this mean the Bactrim is not working.  What do we do then?  I go back to the clinic tomorrow to have the packing on this one changed.Thanks! Jan
