Has Anyone been diagnosed with trigger finger on letrozeole

Hi, I have been taking Letrozole for about a year after changing from tamoxifen. I had alot of pain in hands including my thumb. Maybe this is different to your experience  I would wake up at 3am with my hands all crunched up and in pain. I had to do alot of opening and closing my hands to get them moving. My GP recommended fish oil and it's ok to take from my oncologist perspective. Well my hand pain settled. I still have a little stiffness in the morning but it is nothing like it was. Hope your situation improves for you.
