I have also recently been advised by my oncologist to consider the Zoledronic acid and I am torn. I had lumpectomy and radiation for stage 1B IDC and started on Anastrozole in January. The joint pain really bothered me and we are just now switching to exemestane after a short break. I hope that it is more tolerable. I am very physically active (running and strength training) and only 51. I want to protect my bones for the future. But, like many people who post I am beginning to feel like one drug just leads to another and more side effects.
