Sentinel lymph nodes removed - Chemo & Radiation treatment

Hi everyone   I had my first chemo session yesterday   -  no problems with nausea/vom thanks to everyones helpful tips   -  I did get the furry tongue late evening and used the biotine mouth spray right away.      My breast that had the surgery for lumpectomy is now looking red - (more of a blush than angry) not hot to touch - is this something that is expected after a chemo session.   I had Doxorubicin,  Cyclophosphamide, Pegfilgrastim
