When you are running a fever do they check a cbc count (complete blood count)? If so, are you wbc's elevated (white blood cells)? If so, which ones? Kind of technical but it's helpful to know. If they are thinking that you might have an infection from the port, the only way to know for sure is to culture the far tip of it which could be "seeding" your body with an infectious agent. When you are running a fever, do they give you antibiotics to keep the fever down? Full disclosure- I'm not an MD but these are the questions I'd be asking.
