I am wondering if any here has experienced cellulitis, and if so, what organism was found to be the cause and how that was determined.

 I have been in the hospital since Sat. when the rash first began, although the fever first started right after getting my flu and pneumonia vaccines on Thursday.  The infection is on my upper arms where I received two shots.  They did a CT Scan Sat and did not see any air, abscesses or gangreous tissue, which is good.  I've been on Levoquin and Vancomyacin Sat evening & Sun evening, and today they changed it up to Vancomyacin, Nafcillin, and Meropenum because, while my fever did break, the rash continues to spread.  The blood cultures are negative, which is good since that means it is still just skin/tissue involvement only, but it means we don't know for sure if it is staph or something else.  Just looking for others' experiences.  Thanks!
