Breast Cance
"My OC switched me from letrozole to exemestane because I was having some bone loss. I was a little more tired and achey on the Letrozole so assumed the same from exemesterane but oh my gosh what a difference. I gained 6Lbs in a month, horrible headaches, pins and needles in hands, back pain, fatigue, waking up in the middle of the night, hot flashes, ring in my ears and blurry vision.  I&#039;m switching back to Lettozole at least the s/e are tolerable. I guess everyone is different if it works for others awesome but not for me. These reviews are so needed in our for-profit health-care system. Doctors  won&#039;t tell you or don&#039;t know about all the side effects and who even knows about long term ones....."
