My 30 year old daughter has been running a low grade fever for several weeks. She has a swollen lymph node on her head near the top of her ear, and has been losing weight - possibly as much as 15 lbs. Blood work has shown low lymphocytes and a low to normal WBC. She recently had a UA, which showed ketones, bacteria and blood in her urine, although she had experienced no symptoms of a UTI. She started on Macrobid just a couple of days ago, and has not shown any improvement. She is always tired, but she works full time and parents 3 young children, so she is always on the run. I d welcome any suggestions.
