generic arimidex

[dberg]

It's been a very long time since I have posted, but I knew exactly where to ask this question because this site was a godsend for me 6 years ago.
After 2 years on Tamoxifen I have been on Arimidex for 4 years and haven't had any noticeable joint pain. (Yes, to osteopenia, no libido, etc, but we won't go there!) About 2 months ago I started having aches all over, particularly in one of my legs. I just noticed my prescription bottle says Arimidex (or sub) and wonder if this could be the reason.
I saw the thread where someone actually got better with generic. Has anyone gotten worse?
