Thank you so much for your response. I really do not want to put him through a painful procedure, but it scares me so much when I see him get so pale and in pain. I tell my husband he looks so pale, but it's almost like he's got a flushed "rash" appearance on his face, too. I just want answers as to why he has been so sick so that hopefully we can begin getting him better and back to normal soon. Thank you again. I do have a dr's appointment for him on Monday to discuss this with his pediatrician and will be asking for another blood test to see if he is still anemic and how his wbc are doing now.
