Have been on Femara for about 3 years followng 18 mos on Tamoxifin. Have just beome stiff and have some joint pain-bearable but uncomfortable. What do you know about the dangers to joints etc. of continuing with this. am 73 and have osteopenia.very mild. Dr. has suggested i discontinue for a month to see if pain goes away -- possibly pain is some form of arthritis,osteoporis and aging. Concerned about not taking the drug for fear of recurrence. After 1 month and outcome might change me to arimodex or return to femara. Comments????thanks
