Diane,
Sorry about your long time enduring this. It gets old real quick. I also taking Levofloaxin right now. Because I was running a slight fever. They did bloodwork and my WBC was at 0.7. I had tongue sores fever blisters and just felt and looked horrible. They did some cultures and bloodwork and when I went back on Monday she said the tests came back negative and that my WBC was up again. He only explanation was it was both the Radiation and chemo side affects hitting me at once.
