For me personally, the anastrozole made it so I could barely walk -- between my ankles, feet, back, wrists, and hands it was horrendous. I was next placed on letrozole for which the pains was not quite as bad but gave me migraine headaches. Following that I was placed on exemestane and that had been much, much better. For the hair I read articles on Mayo about women taking biotin for my thinning hair and believe that has helped somewhat. Best of luck to you.
