Excellent incite from New Leaf. I agree that you should investigate further and Carpal is a likely culprit.
My sister had similar severe hand, wrist and up to the shoulder pain as well. The pain was so bad she actually ended up sleeping in a recliner so she cou8ld hold her arms in just the right position. She also has RA like me and just attributed it to that. Then she was recommendtd to get checked for Carpal Tunnel and low and behold that is what she had all that time (still has RA). She found a surgeon who only does carpal tunnel surgery and had one wrist done and was in instant relief. Three weeks later did the other wrist and she has been in heaven since without all that pain.
Get checked for carpal tunnel, worth a try.
PS - the surgery was out patient and recoup very quick.
