DP went into hospital 9 weeks ago and was diagnosed with ostemyelitis with staffy A being the bacteria. 
He stayed on the ward for three weeks and was then sent home with IV antibiotics, he lasted 10 days at home and was then readmitted and has been in hospital ever since, trying antibiotic after antibiotic. He has deteriorated to such a degree now that I am really worried that they cant seem to get the infection under control. Can someone reassure me that they will manage to cure him? What are his chances of full recovery?
