Ring finger pain 2 years after surgery

I had decompression surgery by you, on my right hand in Feb 2022 and on my left hand in July 2022. For the past few months I have had pain in the ring fingers of both hands, which tracks down my hands towards my wrist. The pain is there all most of the time and is an issue when I try to form a fist or hold something, like a steering wheel. The fingers are still and sometimes feel as if they will not straighten or bend. I assumed, at first, that this was arthritis, but it is not like other arthritic pain I have, my rheumatoid factor is normal. Things I have now found on google have made me wonder if this is a side effect of the surgery and whether I now have some nerve damage. I wonder if you could give some advice on this, and also anything I could do to improve my hand function. Thanks
