Hi Danielle,
My father had a rash about 4 weeks into his treatment (chemo and rad.). It started on his stomach and then progressed to his back, chest, and upper arms. It was red and did not itch. His doctors did not know what caused it (there was no change in his medications at the time). After taking Benedryl (sp.) for a couple days, the rash completely cleared and never came back.
At about 5-6 weeks into treatment, he was hospitalized for VERY low WBC count, severe mouth sores, and burns on his neck (bleeding and pussing). They had him straightened out in a week. I know how scared you are, but I'm sure everything will be fine and they will get her counts back up in no time!
My dad has been in the hospital for three weeks and 1 day for severe pneumonia. We thought we were going to lose him, but things have taken a dramatic turn for the better. He is actually coming home sometime this week!
I hope everything works out, I'm sure it will! Take care
