I took femara for 3 years after 5 years of convention treatment with tamaxofin. I had early stage breast cancer with a lumpectomy and radiation in Dec. of 1991. From the time I started femara I had problems but didn't relate it to the drug. Now, five years later I am almost crippled and don't know if it was from femara. I have been going to doctors for since 1995 and it seems like everything else has been ruled out. There have been no answers to my debilitation. I am still undergoing tests. I am presently going to a neurologist and have EMG tests scheduled. Does any one else have experience with femara?
