I have cellulitus in one butt check it's pretty big will I need surgery to remove dead tissue?

So I can't find much on cellulitus after fat grafting i must be the only one. I thought I was healthy , clean , and didn't smoke now 3 infections after lipo- fat grafting to buttucks. The two infections in back lipo area she thinks maybe staph they are draining pretty good . I still get fevers and the cellulitus worries me it will continue to spread if I move? Will I lose half of my new butt? Could I end up in hospital? Will kflex help the cellulitus I just started taking it?
