Hello AT404
Yes I had very similar problems with my hands after a couple of months on Letrozole. I had no grip especially in the mornings! Could not wind up my deodorant stick or get the lid off the toothpaste! I would also wake in the night with painful, stiff, swollen hands.
My GP thought it was Carpal Tunnel and gave me a referral for nerve testing. But before I did that I tried Curcumin capsules. I checked first that it would not interfere with any other medications. My GP said it would not hurt to try but was very pessimistic that it would help.
The result was almost instant with a big reduction in symptoms. I also notice that certain foods seem to make it flare up, so I avoid them! I now have very little trouble with it. I have been on Letrozole (Femara) for 2 1/2 years now. It might be worth a try but please do check that is ok and won’t interact with any other medications you may be on.
