I had stage 1 duct breast cancer one year ago and after a lumpectomy and radiation, no chemo necessary, I am cancer free and have had 2 mammograms recently, proving that. However, I was put on Arimidex at the time and am first experiencing alot of arm and leg pain. I am on other medications also, but have been off of Lipitor, now take Crestor, and have never had this kind of pain before. I am 77 yrs. old. My doctor is highly esteemed in this field and is in NYU Langone. Do you think I should question getting off of Arimidex?
