I'm on femara about 3 years, have the same aches and pains, sometimes just the legs, sometimes all over sometimes nothing at all. Sometimes it's a vicodin day, sometimes tylenol, sometimes nothing, no rhyme or reason that I can figure out and I've given it lots of thought. The one thing that can help is a good nights sleep on a comfortable bed by yourself, no husbands, boyfriends, friends, family, dogs or cats. It's worth it to invest in a feather bed cover, memory foam or egg carton pad or something like that with your favorite pillows. An electric blanket in the winter may help too. The aches and pains were worse for me for about the first 6 months after I started femara, every day was a vicodin day, it's gotten better but has not gone away and doubt it ever will. I guess it's just one of those lessor of 2 evil choices, and I'll gladly accept the aches and pains choice any and every day! Good luck!
