Hi Morry, I have been on Femara since February 2010 (prior to that I had 12 months on Tamoxifen). Femara does cause aches and pains. When I first started on it I had trouble with my feet and ankles, especially first thing in the morning when I got out of bed. I could barely walk, every step hurt so much. After a few minutes I was able to walk much better. These days the pain is much better but still there. I must say I do feel better when I am standing and walking as I seem to seize up if i sit too long. And of course, I feel worse when it is cold. Walking is great exercise for the bones. I play social tennis once a week and I have just started doing a couple of minutes skipping a day ( hoping as my fitness improves I can increase that). My bone density is an issue on Femara and had deteriorated considerably since starting on Femara. I now take a calcium tablet daily and am due for another bone density test in a few months. Morry I don't know how long you have been taking Femara but if it is only months the pain should improve. I think your pain is caused from Femara and I can only recommend doing some exercise as your body permits. Best of luck with it all and keep us informed. Jill
