Terrific to hear your treatment has gone so well ....
Where abouts do you live, @leema? A buddy with Prostate Cancer Mets had quite restrictive Dupuytren’s Contracture in one hand - and a wonderful surgeon in Newcastle did the surgery on him, gratis! Such a wonderful thing for him, as it has enabled him to get back to his offshore kayak fishing, which is one of the 'mainstay activities' since being diagnosed with Mets straight up, 18 months ago. His boney like lumps were quite pronounced & his hand had a real 'claw' like shape ..... if you can get it checked out sooner than later (before it becomes more extreme) it could be worth investigating. I hadn't heard of Rads as a treatment before.
I had quite extreme Trigger Finger on Letrozole (and Exemestane) now on Arimidex (and magic oil) and the trigger finger (thumb in particular and middle finger) has now fixed up!
Take care, all the best with the rads on your hand xxx
