Hey, something just came to me. May be way off, but I know that my son was diagnosed this past Winter with Brown Recluse bites, as was my husband, and what they actually had was Stapholoccocus Aureus (sp?; I always abbreviate it staph). Anyway, theirs was NOT the methicillan resistant kind, but there is such a staph that you cannot kill once it is in your system without something like IV given Vancocillin. I wonder if you need to be checked for what they call MRSA, or meth resistant stah aureus? It can abcess different organs and create many problems. My familys' "bites" were finally cultured, because they were so recurrent, and they turned out to be skin staph infections of the aureus family. Infectious Disease guy said he'd seen a lot of it this year. We'd never sen it at ALL before this, but three members of our family had staph skin infections this past Fall and Winter. They had five or six of them. The sore looked like brown bites, and swelled, reddened and got a cavern in the middle. Could even have BEEN a recluse bite to start, but then became infected with staph. I don't think ours were that, because they were too repetative. Anyway, something I felt I wanted to throw out to you. Hoping you will resolve these problems very soon.
