@ginip your post has great info. How long have you been on Anastrozole? I was on for 2 1/2 yrs. I had taken vacations from the med several times for a month and then 2 months I believe. The relief from hip pain & fog (looking back I was not myself, I describe as a fog over me) wasn’t really improved. After deciding to stop Anastrozole, it took at least 6 months for me to be back to myself. The hip pain was very bad. I could not hardly get in or out of the car or walk.
Have that discussion w/ your oncologist. It would be good to keep a daily log of how you feel each day. It’s difficult to separate out everyday ‘how I feel’ from ‘how I feel being off med’. Blessings to you.
