Arimidex - joint pain

I  have been on it for just over a year and my knees and fingers have never been the same!  I stopped taking my tablets about a month ago (for no other reason that I missed a couple of days when on holidays) and started to notice a difference, so I stayed off them for a week and what bliss!!  It felt so good to feel "normal".  At least now I know it is from those damn tablets and every once and a while I am going to give myself a treat and have a break from them.
