I have been on Herceptin/Perjeta and Femara for 3.5 years now (chemo and radiation in the beginning ) After, about six months i developed a very itchy rash on my arms and chest. My MO sent me to a dermatologist who prescribed a cortico-steroid cream. Anyway, it hasn't bothered me in a year or so. The past couple of weeks, I have a rash again on arms/chest. It is unbelievably itchy and also hurts - it feels like something is pricking my skin from inside. There are pustules that seem to be almost like small blisters. I put in another call to the derm, but am waiting to hear back. I know it's not shingles. Has anyone else experienced this? I have heard that a skin rash can be a sign of new liver mets, but haven't found a definitive answer on it.
Well, thanks for any insights.
