I am so sorry, it is so painful, I am so grateful that mine disappeared after being off Anastrozole, along with the insomnia, joint pain, fatigue, it took six months to feel back to the point I was before surgery. Quite honestly, I knew that's where I was headed. The oncologist said "don't worry if you have bone loss we have a med for that, told her about the side effects, "they have a med for that" and suddenly you have a table full of pills. I also have been told that bone loss meds don't eliminate the bone loss but may help prevent further loss. I know my decision may be detrimental to my future but so were all the side effects. It wasn't intolerable at first but when I couldn't walk and hardly get out of bed due to joint pain, I couldn't continue, it took 18 months to get to that point and another six months to recover from it. Hopefully that is the end of your problems.
