After two years on Anastrozole (generic for Arimidex) the side effects have become too much for me.
I have elbow, wrist and shoulder pain often. I also have some knee pain when I hike or walk long distances.
But the worse side effect for me has been increased emotional ups and downs.
Recently I switched to Aromasin in the hopes that the side effects won't be as bad. But I am also considering discontinuing this hormonal "therapy".
