Whose coping on Letrozole and what brand ? Any tips?

@Arpie no my fingers aren't totally locking just really stiff. I can move them albeit slowly in the morning until they 'warm up'. Last winter my right thumb would give me stabbing pain whilst doing something basic as turning off my car engine or other times when i least expected it. It still happens but not with quite the same intensity. I just don't want the same situation as June July last year hence the want for a 'holiday' then.
