breast cance
"I started taking Arimidex about 4 - 5 months ago as a breast cancer patient.  I'm supposed to take it for 5 years.  The side-effects I'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'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. "
