Hi!
I had a lot of movement in my pointer finger, but it has been that way since birth. I had a small amount of movement in the rest of the fingers, but not much. My hand was able to open maybe 1/2".
As for my carpal tunnel. Since I am hardly able to use my injured arm, the uninjured arm develops problems from overuse. So since my uninjured wrist has been pulling double duty since I was born, it developed carpal tunnel
