How long does average case of stapholuccus aureus infections last. I have been to dr.s 6-7 times within last 2 months , no medical help, just keep pushing oral antibiotics to me, actually getting me worse and most defiantly feeling worse,don't sever cases require iv. Infusions to fully recover. I literally can't get anyone in my area to give me iv infusion with proper antibiotics to feel better, please help
