question: My husband has advanced Metastatic prostrate cancer and has recently had a bone strengthening infusion of Aclasta. He all of a sudden has a very sore arm from his little finger right through to his shoulder and now has little blisters or swollen rash on his finger, inner and upper hand on the side and lower arm and very painful, could this be shingles, he is 80 years old. And is also being treated with Zolodex hormone implant every 3 months. Hopefully I will get an answer Bach soon
