My son is 8 yrs old. When my wife picked him up from school yesterday she thought he looked odd , almost lethargic. He took a nap when he came home and my wife noticed he felt extremely warm. She took him to the local urgent care facility. They gave her some antibiotics ( the pink stuff). Last night he would wake up in middle of night sit on edge of bed almost as if he were still asleep. He was running a fever my wife said he was 104. She took him back to urgent care where they check him for flu. They put some tube in his nose to check. It came back negative. So the doctor asked to be excused and came back and thought my son should have blood work and checked for leukemia. That threw us for a curve ball. There has been other times he has been sick as far as common cold symptoms. There's only so much I can type to try to cover everything I'm trying to get across My question would generally be what are some symptoms of leukemia, and what are the signs.
