For what it’s worth my medical oncologist suggested Krill Oil tablets which I have dutifully taken daily since I started Letrozole. Not sure if they are working but unwilling to come off them.
Letrozole is no picnic and something I was terrified of but I believe it’s the best shot for me so I persist stubbornly.I do believe from my reading on here that women who’ve had chemo find it tougher and I did not have chemo.
The original non generic version of Letrozole is Femara manufactured by Sandoz who make the generic version I use.If a change of brand doesn’t help there are other aromatase inhibitors that people on here have changed to with greater success- that may be worth a chat to your oncologist about.
PS I wouldn’t suggest my exercise has been robust just consistent -an hour daily on hilly terrain regardless of the weather with earplugs on listening to music on my phone to forget I am exercising - but it certainly helped with joint stiffness and I even think my mood - a small daily corner of MyTime.
