Not everyone has such side effects. I’m on this for 15 mos. And I have mild ( sometimes moderate) joint discomfort which IS alleviated with walking and yoga style stretching, and hand exercises and massaging. An occasional Tylenol has been used too.

I’m 72 and I just biked 20 miles ( not unusual for me) walked about 5-6 miles daily while in Italy , I played an hour of tennis yesterday ( in 90 degrees) etc etc

In other words … it is sometimes uncomfortable but not life changing FOR ME. I am lucky that my body can mitigate . I usually react poorly to meds and I was terrified to start Anastrozole especially as I am 98 & 99% ER + ( two foci) My heart goes out to those who have major difficulties; some cannot tolerate the extreme side effects they may get. But many many can and some have no side effects.

My user friendly advice is to try it out if your oncologist feels it will benefit you. It’s a once a day med. if you can’t tolerate it you will know and you can find alternatives… or stop.

Maybe give it a try and see if your body is ok with it. My fears were unfounded.
