Hi Bellaxel
I was prescribed Femara in July 2015 and took if for nearly 12mths. During that time i had really bad lower back pain, pain and 'locking' in the knuckles of my hands - felt like an 80yr old most of the time. I took both magnesium and gucosamine and did not help any - even doubled the dose. i also took supplements fish oil, calcium and Vit D. My doctor took me off Femara and prescribed Armidex instead - said for some reason that no-one can explain switching meds will stop the aches and pains.. The switch has worked for me - i only have mild pain in my hands only, which i can live with, take one magnesium tablet a day (plus fish oil, calcium and Vit D), so feel a lot more comfortable about staying on this for the next 9 years (who is counting)!
hope this helps
