I think we all do this to ourselves at times, I know I do. I have a low WB count, although I do have lupus, my docs wouldn't worry until it was down to 3 or under. Your WB count can go up and down for many reasons or no reason. Please try not to worry too much, it's probably nothing and you'll just feel worse, or come right out and ask your doctor about this. Big Hugs and I hope you feel better soon.
