Thank you! Very helpful to see all the drugs side by side. I'm sticking with arimidex for now. My new trial is the Fosamax I've recently started because of the bone thinning SE's of arimedex. I've had severe thigh pain, my doc at Mayo checked for clots and bone issues, but all were negative. The pain went away after 24 hours, but scared me. I've read so many horror stories about that drug affecting the body adversely. Has anyone used it with minimal effects? I was told to come back in if it occurs again.
