Leukemia

[Guest]

HI, i have a 4 1/2 year old daugher who for the last year has been having fevers. She was having them on a 21 day cycle , the only real symptoms have been a high fever sometimes going up to 105, no appetite, pale, dark circles under her eyes and very lethargic lasting for 4 or 5 days a time. She has urine tests done and it showed blood in the urine, so she is on a medication for a kidney disease(thin GBM disease and is on hydrochlorothiazide)to control her calcium levels) but i am told the fevers are not related. I have fear there is a more serious condition. She has had numerous tests and nothing yet. My daughter just had another fever this week for 4 days. I dont know what to do? could this be a sign of something more serious? She is only 32 pounds and when she goes through this cycle she loses weight. I can almost see it in her a day before the onset of the fever, she gets tired and says her belly and legs hurt. she also complains of headaches. PLEASE HELP!
