Welcome to HCM.
Rocky mountain Spotted fever
is one of the serious infections caused by small bacteria called Rickettsiae. It is one of the infections which has to be treated in the early few days for better results. The long term problems for this disease are common for patients who are hospitalized for more than 2 months. One of the common problems is neurological deficits in fingers, arms and legs. I suggest you get a neurologist
opinion for the knee pain
MRSA is methicillin resistant staphylococcus aureus
which is a common pathogen found in hospital associated infections.
Lab tests can be done to confirm MRSA. Get in touch with your GP for guidance regarding this. Thanks.
