my mom got bit by something awhile back I believe it was a spider. I think she got MRSA from that. She wont go to the doctor, but now she is running high fevers Her leg where she was originally bitten has a large pitted looking wound, and is swollen, hot to the touch, purplish-red in color, she is itching like crazy. Is it possible for MRSA or some other kind of severe infection to have gotten in her blood stream.
