Hi Katy
I’ve been on anastrazole for just over a year (started January 2013). I have the same problem with fingers only it’s my middle finger of both hands which are mainly affected (how is a person supposed to drive when she can’t salute other drivers). I did mention to doctor when I was last there but all I got was a grunt as this was not my main reason for visit. I took it that the grunt meant ‘tuff’, so let it go. My hands are usually stiff/sore in the morning (hands feel as if they are swollen) but ease out as the day goes and stiffness returns of an evening. I have no arthritis that I know of but I can certainly feel the difference when walking up stairs, knees are stiff but as I’m 67 now I just put it down to getting older.
