Breast Cance
"I started taking Arimidex about 4 - 5 months ago as a breast cancer patient.  I&#039;m supposed to take it for 5 years.  The side-effects I&#039;ve experienced are: insomnia, hot flashes, headaches, weight gain, joint pain, and severe loss of grip in both hands. My hands are stiff in the morning and evening, it&#039;s just crazy.  Well, even throughout the day.  I asked my oncologist about this and he said it was arthritis, which I do NOT believe.  The onset was too quick.  It was about 6 weeks after I started taking the Arimidex then the hand stiffness showed up. "
