Hit the first real snag in my treatment yesterday (considering that everything up until now has run very smoothly). My white blood cell count went below some critical level that now has me at an "extreme risk of infection." They've put me on Neupogen to stimulate my body into generating more white blood cells and with any luck, my blood test tomorrow will have me back up to acceptable levels and my chemotherapy treatment next week can continue on schedule. The unfortunately side-effect of this is that I'm suffering some serious bone pain. Hoorah for Tylenol which seems to be saving the day for now.
