I did have a low white blood cell count during my chemo after every treatment they put this “Neulasta” gadget on my lower abdomen, and it gives a injection that boosts your white blood cell count. You wear it for 27 hours. You need help when you remove it they put it on you at the infusion center. I never had any problems after receiving this. I got one right after every treatment following the first drop in my white blood cell count.
