Gosh, @FLClover - just like you, my legs, feet and hands took the brunt of it on both Letrozole and Exemestane (it gradually got worse & worse til at 6 months I wanted to stop.) I was put on short doses of Prednisone when it got really bad - but that is not good for your bones, so shouldn't be relied on. I couldn't even play my ukulele at one stage!! grrrr
I am MUCH better now tho, on the Arimidex! If you are in discomfort & pain, give it a go! I am much happier on it! xx
