One word BAD for me. After 18 months in Anastrozole I fought with my oncologist to change me meds. I was put on exemestane and I take this 4 times a week. I read an article by an oncologist who said that he didn’t think it necessary for women like myself who have a bad reaction to the meds, to take it ever second day. My back pain has improved, slightly, and I’m walking and swimming again. At the beginning of treatment I could hardly walk. Joints are painful but that is wear and tear age related. I had mri onn13 july for my back and all is good. Best of luck with your treatment. Xx
