Hi Lisa, I have been on Femara now for 18 months. Most of my side effects didn't kick in till about the 4 month mark. Your description of standing up from a sitting position or on the floor is exactly what happens to me, and early on, even rolling over in bed caused pain. I hate my stiff fingers and swollen finger joints, but I have discovered that large doses of fish oil really do make a huge difference. I take the triple strength capsule morning and night. ( I always forget about the midday one.) I have been doing this now for over a year, and it really does help. Good luck with it all. Love Chris xx
