Suggest bone marrow puncture, if leukemia is not ruled out, it will be difficult to treat, and there will be a lot of blood transfusion to see if you have lost blood components. Generally, there is no whole blood transfusion, and there is no leukocytosis in the case of blood components, so a large amount of blood transfusion will not cause leukocytosis. (As long as you don't lose white blood cells, blood stations generally don't divide this. )
