I have had cortisone injections in the past for trigger finger. That was w-a-y back 20 yrs when I was 'abusing' my hands/fingers when I tried to carry too many bags by looping them over my fingers. I discovered that was the reason, after I retired, and didn't need to haul so many teacher things with me everyday.

My husband has Dupuytren's Contracture. His symptom was that he could not open his hand completely, one finger was the main culprit. And he had a hard knot in the palm of hand. PCP referred him to orthopedic surgeon who wanted to do surgery, however husband decided to seek a 2nd opinion from a hand surgeon. The hand surgeon did not even mention surgery. The hand surgeon said that he needed a ziaflex injection. So he got the injection. That was around 6 years ago. We remember that he had a bandage afterwards, but he does not remember any pain involved. 2 Days after the injection he had a follow-up and he could completely flatten his hand, so we knew that it had worked. The doctor gave him a soft finger splint to wear at night. It was his ring finger, and I only remember that he wore his wedding band on his right hand for a little while.
We know that hid dad also had Dupuytren's. But back then, there was no treatment available.

We are currently aware that the knot is returning and he is considering getting it checked agin. He is okay with getting another injection.
He has never experienced any pain associated with his hand.

@scardycat, It sounds like you are considering a ziaflex injection, for my husband, the surgeon said that when he could not flatten his hand on a hard surface - it was time to consider it. We are both completely amazed at the different treatments offered by the orthopedist and the hand surgeon. Who is treating you for this?

@capausz, When I was getting the cortisone shots that I mentioned above, I found out that my watchband was causing pain. We think it was irritating a nerve (?) - Any I have stopped wearing a watch on that wrist as a result. I do hope that you will be able to comfortably wear your wedding bands. Will you share what you find out about the pain in ypur ring finger?
