Hi @Josephine66
Yes, Letrozole can be a real 'Pain in the Proverbial' .... I was on it for about 6 weeks initially and found it incredibly painful - with everything aching (for a 1% chance of reducing recurrence!) So I had a chat with my oncologist & I swapped over to Exemestane - and I've found it much less painful!
There is another thread that pretty well covers most things that might arise now & in the future if you stay ON Letrozole - should you like to check it out!
