Hi Cassie,
I have been on Femara for 3.5 years now, and I had all those side effects too. Now I am pretty good, though can still walk like a 90 year old for the first few steps in the morning. I had ankle swelling, but it hasn't been an issue this year. My joints and tendons seem to be better if I take fish oil and krill. This year I have even started seeing a personal trainer at the gym (I hate gyms). I realised today that I can now squat down and get up again without needing to haul myself up using the furniture. So, the exercise has helped my knees and added lots of strength. Even the hot flushes aren't as bad as before. I still get some, but the intensity has come out of them.
It is a bugger, but I am just pleased like Dawn, to have this drug to reduce the chance of recurrence. I have no desire to stop taking this drug till I get to the 10 year mark. I hope your side effects will start to ease soon.
