Suggest Treatment For Diarrhea And Fever After Hip Replacement Surgery

Hello, My mother was in a rehabilitative center for hip replacement surgery . She had severe diarrhea & fever resulting in C. Diff infection. She was quarantined for several days (in a quarantined room). She said she didn t fully recover (for the hip replacement). She s in a walker now and has oxygen (from the other hip) from years ago, but it s on a moderate level of oxygen (not on low). She can hardly walk across the hallways of her independent living community. What are your recommendations?
