My father (63) has been having on and off fevers for the past few days, three weeks post his surgery. He has an appetite and is not in significant pain, besides his stomach feeling "off". He is also just very tired, likely from the fever. His bloodwork only shows high white blood cell count, likely from some kind of infection. He went on antibiotics and they worked for a week (no fever), but then the fever came back and he hasn't had a below 99 temp for several days. The doctor just took his bloodwork again and hasn't called to discuss next steps. Cholangitis? or should we be pushing for anything else?
