Arimidex

I have been on Arimidex for three weeks and have found that my joints have become very painful- my hip is the worst  but my fingers are stiff and my fine motor control is getting really bad-  could not even crochet yesterday. I have had arthritis since I was 9 and have had it under control for the most part,  but an now feeling terrible.  Have noticed some swelling of feet also.   I hope this improves.  Still having problems with the after effects of taxotere so am not sure which side effects are from which drug.  I do not like being on this drug cocktail they have got me on.
