Call your doc and report what's going on. He may be having problems with one of the antibiotics and may need to change to something else. And the presence of a fever isn't good, so make that call.
I have called the ER and they won't tell me anything, just that I can bring him in if I want to. The hospital is a half hour away so I am watching him close and I am going to call our Dr. in the morning. Thanks.
