My husband went to the dr. earlier today for a sinus infection and ear infection, the ARNP said she was going to give him a steroid shot and gave him omoxicillan, however, he usually after the steroid shot feels instantly better within an hour or so, this time he began to instantly get worse, flu like symptons and fever of 101.1. he was not running fever prior to this. My fear is that she mistakenly gave him a flu shot instead, which would explain how the symptoms changed, b/c that s how he always gets within a few hours after a flu shot... Please advise as to if I m thinking incorrectly. Thanks
