Letrozole
"Yesterday I completed five year on Letrozole!  Over the past two years I have had awful joint pain in my knees, outers thighs and wrists.  My body aches all over and I feel exhausted every day. I wake in the morning with stiff hands and fingers. My oncologist has now taken me off letrozole as I have completed my five years and told me that my aching body and joints should gradually get better."
