Debilitating fatigue with Arimidex?

Arimidex almost incapacitated me by the time I'd been on it for almost a year. I had brand new joint pain and was exhausted and incredibly weak, even though I'd been very active for my age (67). My doctors pooh-poohed it as not being due to the drug and I constantly got the message that it was "just my age" even though I never had the problems before beginning Arimidex.

The final straw, for me, was when it began to affect my head--I'd feel a weird wave of dizziness begin at the back of my skull and sweep forward, leaving me very scared and barely able to balance. Before beginning the drug, my balance had been excellent, especially for someone my age. So I gave up on ever getting a doctor to believe it was the drug and simply notified them that I was stopping and why. That was hard for me to do, for so many reasons.

But in 24 hours I felt MUCH better and the dizzy spells had stopped completely (after having had at least 2 dozen of them the last day on the med) and in 48 hours the fatigue was gone and I finally got my energy back. I refused to go on Aromasin until my poor body had had at least a 2-3 week vacation from any anti-estrogen drug. 

When I finally started Aromasin, the joint pain worsened again and for the first time I got a bizarre severe pain in the palm of my left hand when I woke up every morning. Not trigger finger, but in the finger bones inside the hand. It was there each morning for months, then 2 days ago it just went away--! No idea if the relief is permanent.

And now I have 4 more years on these drugs--I'm really worried that they're destroying my joints, but want to increase my time without cancer. So I guess I'm stuck on them. Not happy about that.
