Another way of looking at the side effects of aromatase inhibitors

I’ve been on Anastrozole for 2 years and suffer badly from joint and muscle pain on a daily basis. However I read in an article on line that the unpleasant side effects of anti estogens can indicate treatment is working. Women with side effects were found to have better breast cancer free survival compared to those with non specific or no side effects. Latest research links certain side effects to better survival outcomes.  
I certainly don’t believe all that’s written on line but I’m taking the view now that all this pain Im going through shows that Anastrozole is doing it’s job and for that I’m grateful! And if it leads to a more positive outcome then that really is a bonus.

I’m not sure if I’m able to post the website on here or not but there was a lot of advice on diet etc as well?
