I have been taking Letrozole for 4 years now and I wanted to ask does any one have severe joint pain all over my body. It started in my lower back now I hurt every place on my body and I have also gained so much weight in just the stomach area. I have terrible hot flashes and it is terrible to be outside in the heat. How long do I have to be own this drug and is there any help for the side effects. Thank You, Geora Zolman
