It can cause joint and muscle aches/pain. I assume anywhere - my hands, toes & shoulders hurt. I'd check with your doctor, because it may be unrelated.

I agree with Kathy. Anastrozole gives many of us joint, bone and muscle pains, here and there, and now and then. At our ages, it's convenient to blame everything on anastrozole, but there may be other issues going on for us (like cervical stenosis, for example). If it's muscular, doing gentle neck/shoulder exercises each day may help. If it's vertebrae-related, the exercises won't help and may even hurt the situation. It's best to have a doctor's feedback.

It’s interesting to hear this. I have been taking Letrozole (Femara) for 2 months and have constant pain when I move my neck. The pain even shoots up to the left side of my head. Since it’s not not listed as one the side effects (the neck is not a joint is it?) I’ve assumed it’s unrelated, perhaps to my left shoulder that I fractured over a year ago. I don’t think it’s an aneurism because it only happens when I move the neck. I also feel like I’m having cognitive issues, this is also not a list side effect. I had lumpectomy and radiation, no chemo. I’m 69 and active - walking and yoga every day. I definitely understand the benefits of taking the AI and will keep doing so. I’ve been wondering if it makes any sense to switch from one AI to another since all three seem to have the same chemical reaction in the body (maybe Aromasin is slightly different). I have my first appointment with an oncologist 10/23. Wondering if I should bring any of this up.
