Bone and joint aches and pains seem to be my worst side effect too. I’m on Exemestane now. I was on Anastrozole which gave me brain fog so badly I couldn’t think straight, and thought I was sliding into dementia. My doctor then switched me to Tomoxifin and I had similar side effects to the Anastrozole. I switched to Exemestane about 6 months ago and it’s ‘tolerable’. I keep expecting to be able to eventually go back to the person I was before my breast cancer diagnosis, but I’m beginning to think that will never happen. I’ve learned to ‘console’ myself by being grateful that I’m alive and for the medication available to us helping to keep cancer away. I’m 66 and looked forward to my retirement from work for many years! Now I feel like an an 80 year old woman due to medication I must take to keep cancer away...
