I HAD A PROCEDURE DONE ON MY FINGER AND DEVELOPED A SSI but the surgeon refused to test the
Infection saying that I did not get it from him I HAVE SPENT 10 MONTHS TRYING TO GET HELP AND THE MRI SHOWS IT WENT TO THE BONE BUT STILL THE HMO HAS RESORTED TO TRASHING ME TO ER and other doctors they want to stop any form of biopsy so I am left really sick and now my son is showing weird sighns of some kind of infection my whole body ie riddled with pain why am I in so much pain and why would a surgeon do this I am suffering so much
