I came across a thread about Letrozole and learnt that there are different manufacturers (I never knew this). I was taking the Cipla brand and recently changed to TEVA after reading about the experiences of other ladies. Changing brands has made a difference to my aches and pains. Perhaps changing brands may help you too? Otherwise definitely let your oncologist know about your neck pain.
All the best
@Carol1960 where did you get to with this? Did you try another medication instead? I hope you are ok I too am on letrozole & am also considering changing medications as my neck and head are so bad :(.
I have spoken to my oncologist & he is doing MRIs also.
I put up with letrozole and another one in the same ‘family’ of drugs then oncologist said to change to Tamoxifen. Might be worth you asking. Not that Tamoxifen doesn’t have it’s side effects but not the pain in joints I got with Letrozole.
