I feel your pain! I was only On an anastrozole for six months. I have trigger thumb a baby fingers don’t work knee pain all the joints in my body hurt. And yes, I went off of it. I have more energy, but the pain is still bad in my fingers and my thumb. I was thinking about calling a rheumatologist for help. Yes, I am also scared that I went off the pill but can’t live my life on the couch. I am a very active person with a very active social life. Best wishes and hugs to you.
