Joint and muscle pain with exemestane

I started taking exemastane after trying anastrozole ,the anastrozole i took for a month and had painful joints and muscels,my dr. Let me stop and now am trying the exemestane. I am now in even more pain!! I talk to her next week to see what I can do,I don't see how i can do this for 5 years!!! Im hoping there's something I can take or if I can try some integrated medicine if my insurance will cover it. I'm just not sure what to do? My dr said most of these meds have similar side effects. ??
