I took Anastrozole for a year and a half. I had no libido. My husband said I was not myself. I was depressed and just not happy. I was losing interest in doing things I enjoyed. I decided to stop taking it six months ago to see what would happen. Within a short time those symptoms went away and I was back to my old fun loving self. Now, however, I am having aches and pains in places that that were never a problem and were not injured. It seems to be in various tendons and muscles. The pain moves around from behind my knees to the sides of my knees. I saw my regular doctor and told her. She is not my prescriber of the Anastrozole but thinks these symptoms I am having may be related to going off the medication. Has anyone else had this problem?

@mboat123, are you taking another kind of aromatase inhibitor or tamoxifen?

I have taken anastrozole for 5 years. Over that time I have experienced joint pain, especially in my knees. This winter my pain got worse and the way you describe what you are experiencing is exactly how I would describe my pains. I assumed it was related to other things. I have now stopped taking anastrozole and the pain around my knees is becoming unbearable. The pain comes from around the knee and there is stiffness in the joint and yes it does seem to be in the tendons and moves around not always in the same place. It is very uncomfortable when I try to sleep at night. Hopefully this is withdrawal symptoms and will go away in time. Thank you for sharing what you are going through as I hadn't made the association with the pain to ceasing the medication until I read yours and other similar stories
