Hi AT404, I have similar issues in that the thumb joint base on both hands is really tender and it doesn't take much for it to grab and then a few choice swear words erupt, simple everyday movements that normally you wouldn't think twice about. And yes my fingers crack and crunch sounding like a bowl of cocoa pops. Occasionally it hurts, most times it doesn't. My oncologist has seen how swollen my right fingers can get. There is the start of arthritis in them but before BC i had little trouble. One of the other AI drugs is steroid based (exemestane) but i don't know that you'd want to go down that track or whether it would be effective. Definitely a question for your ocno. 2 hours in the garden doing what i would consider simple things, nothing heavy and my hands are screaming at me the next day. Warm water, gentle stretching and funnily enough, free weights work (lying on your back on a foam roller, holding up a pair of 1-2 kg weights in your hands and doing some shoulder protraction retraction work) This at least works for me in easing the swelling which then mobilizes my fingers and hands and loosens my shoulders at the same time. Bonus! Does all this stop me from doing what i want? Nope! I just have to pace myself and recognize my limitations. Hmmm recognizing my limitations, i might need to work on that particularly after my work in the garden last weekend!. Ah well, if you don't use it, you'll lose it! Oh and i've been on letrozole for 9 months and for me it's gradually got worse. I'm hoping it'll ease with time. Let us know if your onco comes up with any useful pearls of wisdom. Cheers Cath
